Video assistant referees will be used at the World Cup for the first time in this year's finals in Russia, FIFA president Gianni Infantino says, and teams will be allowed a fourth substitute in matches that go to extra time.
The International Football Association Board unanimously approved the inclusion of VAR at the tournament in Russian Federation at a meeting earlier this month, and world football's governing body has now backed the ruling.
The FIFA Council convened on Friday in Colombia, where president Gianni Infantino confirmed the decision had been taken to use the controversial technology.

"It's an essential, important and historic decision, based on the meeting of IFAB two weeks back".
"A decision based on trials carried out on over a thousand matches, provides us with guarantees that VAR definitely helps referees - will help for us to have a more fair and transparent sport".
FIFA Council member Reinhard Grindel tweeted that clear communication would be important to make the system a success.
Infantino said that VAR had been shown to reduce the number of refereeing mistakes in matches where it had been used. "What we want to do is avoid resounding mistakes by referees".More news: National Football League free agent rumors: Patriots agree to deal with DE Adrian Clayborn
Suarez, who led Ecuador at the 2006 World Cup in Germany and Honduras in 2014 in Brazil, remains a fan in general of the use of technology in football, which he has witnessed close up.
Controversy has been stirred even by the most experienced VAR officials who have handled many more games than most referees who will work at the 64-game World Cup.
The long-awaited decision to use VAR at the World Cup was finally confirmed by Federation Internationale de Football Association on Friday.
But FIFA have made a decision to harness the technology in Russian Federation after it has previously been used on the global stage at the 2016 Club World Cup and last year's Confederations Cup.More news: EU Powers Exploring New, Non-Nuclear Sanctions On Iran
