The latest tweak follows so much controversy regarding Julian Alvarez's disallowed spot-kick during the penalty shootout between Atletico Madrid and Real Madrid, in the Champions League round of 16.
The Argentina international slipped and inadvertently touched the ball twice when scoring past Thibaut Courtois, with VAR picking up the fault, and the strike being overturned.
Atletico went on to lose to their fierce city rivals.
Consequently, after a review, IFAB have clarified the penalty-kick law, stating that such instances will now result in a retake.
"When the penalty-taker accidentally kicks the ball with both feet simultaneously, or when the ball touches the penalty-taker's non-kicking foot or leg immediately after they have taken the kick, if the ball enters the goal, it will be repeated.
