UEFA is proposing a major rule change for yellow cards.

Under the plan, a player could be temporarily removed from the pitch if a foul they committed causes injury to another player.

UEFA's chief refereeing officer Pierluigi Collina says the current system is not fair, as the team of the person receiving treatment has a numerical disadvantage.

"The current system isn't fair. The player who commits the foul is only cautioned and stays on the pitch while the team with the injured player is left a man down," he said.

The proposal will be put forward to the International Football Association Board at the start of next year.
