Goal-line technology approved by FIFA

Updated July 06, 2012 07:20:06

Goal-line technology to confirm whether or not the ball has crossed the line has been approved by world soccer's rule makers, ending a decade of debate and controversy.

The International Football Association Board approved the use of two different technology systems which FIFA secretary general Jerome Valcke said would be used at the 2014 World Cup in Brazil.

"We have decided to use the system at the Club World Cup in Tokyo (in December), at the Confederations Cup (in 2013) and the 2014 World Cup," Valcke told reporters.

The IFAB also approved the use of five-man refereeing teams, featuring an extra linesman behind each goal-line in addition to the two on the touchlines.

These have been used on an experimental basis recently in several competitions including the Champions League and Euro 2012.

Pioneered by UEFA, the system was credited at Euro 2012 with reducing the amount of pushing in the penalty area as well as cutting down on players attempting to win penalties by diving.

"The IFAB has been around since 1886, it's been the guardian of the laws of the game all that time, it has developed slowly, conservatively and carefully to try and improve the game on a worldwide basis," said Patrick Nelson, a board member from Northern Ireland.

"The decisions we made today are all ones which will be long-lasting and will resonate throughout the world and they have been taken very carefully."

"The IFAB has made some very good, fundamental and momentous decisions here today," added Jonathan Ford from Wales.

Goal-line technology will be used in incidents where it is impossible for match officials to determine with the naked eye whether the ball has crossed the goal line.

These would include cases where it bounces down off the underside of the crossbar and is cleared away by a defender.

Pressure has been growing on soccer's governing body following a series of high-profile incidents over the years where teams have not been awarded goals even though the ball has clearly crossed the line.

The most prominent was at the 2010 World Cup when Frank Lampard's infamous phantom goal for England against Germany in the 2010 World Cup finals was disallowed when it was clearly over the line. Germany, leading 2-1 at the time, went on to win 4-1.

FIFA president Sepp Blatter told the BBC: "We didn't have accurate systems in the past, after what happened in South Africa, I have to say 'thank you Lampard', it took me a day to recover, I was really down and shocked."

Valcke said two systems had been approved, Hawk-Eye, which is used in tennis and cricket and is based on optical recognition with cameras, and GoalRef, which uses a magnetic field with a special ball to identify a goal.

He said that competition organisers would be free to use either system, the only two of ten initial candidates to pass FIFA's rigorous testings.

However, systems would have to pass another test at every stadium in which they were installed.

The decision was made despite an appeal from UEFA president Michel Platini who said it would open the way for the further use of technology.

"We are not considering any more technological advances here, we are only looking at technology on the goal line," said the English FA's Alex Horne.

"We do not think its appropriate for technology to creep out onto the field to interfere with other decisions, anything beyond goal line technology decisions begins to undermine the authority of referees."

The IFAB comprises four representatives from the British associations, who hold one vote each, while FIFA has four more votes.

FIFA also announced a ban of the Islamic headscarf, or hijab, for Muslim women footballers would be lifted.

The garment had previously been banned due to safety concerns and because it was not recognised in the laws of the game.

The International Football Association Board (IFAB) unanimously overturned the ban and agreed to re-write the laws after studying reports from FIFA's medical officer.

"Safety and medical issues have been removed for the use of the headscarf and it is approved that players can have the head scarf," Valcke said.

Goal-line technology a must: Blatter

Updated June 20, 2012 22:57:09

FIFA boss Sepp Blatter said on Wednesday that the introduction of goal-line technology is a must after Ukraine's apparent equaliser against England in their final Euro 2012 group match was not awarded.

"After last night's match #GLT is no longer an alternative but a necessity," the president of football's world governing body Sepp Blatter wrote on Twitter on Wednesday.

Blatter has frequently stated his position in favour of technology to determine disputed decisions, setting him at odds with his counterpart at European football's governing body UEFA, Michel Platini.

Platini this week told reporters in Warsaw that the five officials currently being used in Euro 2012, including two on the goal-line, would prevent any repeat of controversial incidents.

He again said that technology was a slippery slope towards its use for every decision, including off-side and handball.

But the five officials at co-hosts Ukraine's final group D match with England in Kiev on Tuesday were under scrutiny after Marko Devic forced a save from Joe Hart in the 62nd minute and John Terry cleared off the line.

Television replays suggested that the ball had crossed the line for a goal but Hungarian referee Viktor Kassai waved play on.

"The result of the match turned on a gross error by the officials who didn't give the Ukrainian goal," Ukraine's Sport-Express newspaper said on its website on Wednesday.

"And it all happened with five officials, two of whom were in charge of seeing whether a ball crosses the line."

It had not been the case the previous evening when Italian striker Antonio Cassano benefited from a sharp-eyed fifth official who correctly called that his header had crossed the line in the 2-0 win against Ireland.

FIFA is currently trialling two prototypes of goal-line technology, one from British firm HawkEye, which uses a series of cameras in stadium roofs to track the trajectory of the ball and another from German firm GoalRef, which uses sensors.

Both have been tested in match conditions in recent months, with monitors observing the performance of HawkEye during England's pre-Euro 2012 warm-up game against Belgium at Wembley stadium.

Also on Wednesday, UEFA's chief refereeing officer Pierluigi Collina, admitted the goal should have been given.

"The ball crossed the line. That was unfortunate," Collina told a news conference in the Polish capital, Warsaw, the day after the match in Donetsk that England won 1-0.

Collina blamed human error for the call but said two similar decisions in the 24 matches so far played in the tournament had been correct, adding: "The third, unfortunately, was wrong."

Modern Technology has Given Us a Wonderful Range of Sports Sunglasses


Modern technology has given us a wonderful range of sports sunglasses frames and sports sunglasses lenses made to both enhance and stand up to the demands of the sports enthusiast with lightweight, flexible, durable materials, no-slip frames and a wide variety of lens options. The sports sunglasses and discount sunglasses are made to suit whatever sporting activity you might be considering whether it be golfing, skiing, snow boarding, playing tennis, motorcycling, cycling, kayaking, boating, water skiing, fishing, mountain climbing, snow shoeing, mountain biking, playing baseball, running or jogging the options have never been more abundant.

One of the most important aspects of the sports sunglasses is the lenses. The optical quality and visual enhancement of sports lenses has never been better. Lens colors such as brown, yellow, green, gray, rose, amber and orange can help enhance your sports performance by filtering out colors and allowing you to see what is most important. Polycarbonate lenses are a popular choice as they are impact resistant and very strong which is helpful when it comes to sports. Having lenses that are impact resistant is also a necessary factor when it comes to children wearing sunglasses, impact resistant means the lenses won't shatter if bumped or knocked.

The sports sunglasses frames available are just as important as the lenses you choose. Sports sunglasses frames can be found in lightweight and durable frame materials such as polyamide which keeps it shape even when under stress. Goggle frames made of softer flexible materials like rubber, nylon and propionate prove to be excellent as they hold their shape and will not become brittle in the cold temperatures when skiing or snow boarding and therefore will not injure your face. It is possible to find good quality discounted sunglasses, replica sunglasses and sports sunglasses frames to accommodate whatever sporting activity you choose to participate in.

When it comes to sports sunglasses polarized lenses are another popular option as they are ideal for water and winter sports where water and snow can increase the reflective glare, especially on flat surfaces. Polarized sunglasses lenses absorb approximately ninety eight percent of reflective glare offering glare free vision for your sporting activities. Polarized sunglasses are excellent choices for boating, water skiing, skiing, snow boarding, golfing, motorcycling, cycling and jogging with polarized lenses also available in ski goggles. Polarized sunglasses come in a wide variety of designs, colors and styles and can be found on discount sunglasses sites at affordable prices for everyone.

With so many wonderful sports sunglasses, polarized sunglasses, discounted sunglasses and replica sunglasses to choose from you might have difficulty selecting just one or two pairs of sunglasses. With that said the following are just a few of the sports sunglasses trends you might encounter and can include; no-slip temple grips and nose pads (quite often made of rubber); polarized sunglasses lenses that enhance sports performance by absorbing ninety eight percent of reflective glare; lightweight and durable sports sunglasses frames made with polyamide which keeps it shape even when under stress; sports sunglasses with changeable lens systems that allow you to use dark lenses under sunny skies or clear lenses for darker conditions; and sports specific sunglasses with color enhance lenses.

Ski goggles like sports sunglasses have also benefited from modern technology with the materials used to make them. Ski goggles not only provide protection for the face but for the eyes as well, with some ski goggles covering the whole upper portion of the face (smaller goggles are also available). Ski goggles are made with a lens area large enough to give the wearer a wide field of view and good peripheral vision. Unlike sports sunglasses ski goggle frames are made of softer more flexible materials like rubber, nylon and propionate as they hold their shape and will not become brittle in the cold and injure your face. Available in rose, yellow-orange and pink tints ski goggles allow you to make out the shapes, objects and bumps in the snow. Like sports sunglasses ski goggles are also available with polarized lenses which filter out the glare.

Due to the large number of sports related eye injuries each year, the importance of athletes wearing protective sunglasses and sport eyewear becomes obvious.

Whether you wear ski goggles for snow boarding and skiing or protective eye shields made of polycarbonate (impact resistant) for baseball eye safety is necessary.

Sports sunglasses will not shatter or bend like regular sunglasses might. Another reason for wearing protective sports sunglasses is simply for their UV (ultraviolet) protection, you should look for at least ninety eight percent UVA and UVB protection when selecting your sports sunglasses because without proper eye protection keratitis (sunburn) of the eyes can occur. The tinted ski goggles available can also assist with seeing the subtle bumps and lines of the ski hill which in turn can ensure your overall safety.

A popular trend in sports sunglasses is that of sunglasses for enhancing sports performance. Some of the sports enhancing sunglasses can include; yellow tinted sports sunglasses used for tennis where the balls are usually yellow; green tinted sports sunglasses excellent for golf as they give more contrast and visual acuity so the objects in the course such as flag stick and ball will stand out; specially tinted sports sunglasses for trap shooting and baseball; amber or rose ski goggles which enhance the soft grays that mark shadows on a ski slope, these shadows allow you to distinguish the ridges or bumps in the surface. The sports sunglasses that you select should also offer protection for your eyes.

There are sports sunglasses available for whatever types of sports you and your family are interested in. Whether you purchase your sports sunglasses or polarized sunglasses from discounted sunglasses, replica sunglasses or fake sunglasses sites you should always be sure that the quality of your sports sunglasses is high. By selecting high quality designer sunglasses lenses and sports sunglasses frames you will be protecting your eyes from damage, while at the same time enhancing your sporting activity to the fullest.
