Football's world governing body has banned pitchside television monitors at the Confederations Cup after a controversial late penalty earned Brazil victory in their opening game.
FIFA'S president Sepp Blatter says there'll be no more video in front of the fourth official on the side of the field so no one can say it interfers in any decision.
Egypt, beaten 4-3 by the former world champions on Monday after a last-minute spot kick by Kaka, appealed against the result.
The Egyptians said the referee changed his decision to award the penalty on the basis of video evidence transmitted to him by the fourth official on the side of the field.
Webb originally blew for a corner after a shot was cleared but changed his decision and sent off an Egypt defender for hand ball.
FIFA rejected Egypt's appeal, saying Webb changed his mind after consulting his linesman.
