Semi-automated offside technology will be used at this year's World Cup in Qatar.
It will be the first time that the technology has been used at the FIFA men's World Cup.
The technology will see video match officials receive offside alerts, with decisions validated manually before being communicated to the on-field referee.
It has been successfully assessed at the 2021 FIFA Arab Cup, as well as last year's FIFA Club World Cup.

Communication with fans inside stadiums will also be improved as a 3D animation will be displayed on big screens.
Television viewers at home will also be shown how the offside decision was reached.
Speaking on the topic, FIFA president Gianni Infantino said: "Semi-automated offside technology is an evolution of the VAR systems that have been implemented across the world.
"This technology is the culmination of three years of dedicated research and testing.
"FIFA is committed to harnessing technology to improve the game of football at all levels, and the use of semi-automated offside technology at the FIFA World Cup in 2022 is the clearest possible evidence"
The new technology uses 12 dedicated tracking cameras mounted underneath the roof of the stadium to track the ball.
It also has 29 data points of each individual player, 50 times per second, calculating their exact position on the pitch.
The 29 collected data points include all limbs and extremities that are relevant for making offside calls.
