Palmeiras is trying to have its 2-1 loss to Internacional in the Brazilian league annulled because the referee allegedly used television images to disallow the team's second-half equalizer.
Palmeiras has officially filed a protest with Brazil's sports tribunal and requested a rematch because of the referee's decision to change his call in Saturday's match.
Argentine striker Hernan Barcos used his hand to score the 62nd-minute equalizer, but the goal initially stood as neither the referee or the linesmen saw what happened.
Internacional players protested and the referee reversed his decision nearly five minutes later after talking to his assistants on the sideline.
A TV reporter said a match delegate and fourth official asked the media if replays showed the handball.
