Tottenham are to appeal against the red card shown to Danny Rose in Wednesday night's 5-1 Barclays Premier League defeat at home to Manchester City, Press Association Sport understands.
The 23-year-old was sent off by Andre Marriner after the referee awarded a penalty following Rose's challenge on Edin Dzeko, although replays suggested the Spurs full-back got a touch to the ball.
The hosts were losing 1-0 before the spot-kick, which was despatched by Yaya Toure, before City went on to score three more goals - with Etienne Capoue grabbing a consolation for Tim Sherwood's side.
Assistant referee Scott Ledger flagged for the foul, with Marriner originally having signalled for a corner before siding with his colleague and pointing to the spot - with Rose dismissed as a result.
Tottenham head coach Sherwood suggested after the game that he was considering lodging an appeal against the decision, with Rose currently ruled out of clashes with Hull, Everton and Newcastle.
''I think Andre got it right in the first place when he called it as a corner,'' Sherwood said in his post-match press conference.
''Unfortunately for us, the linesman decided that Andre got it wrong and he's given a penalty there. I think Danny's making a last-ditch tackle so he's having to lunge in there a bit. He clearly wins the ball - I think we will appeal."
City moved top of the standings courtesy of the win, and their manager Manuel Pellegrini was at odds with Sherwood's views of Marriner's decision.
''If you ask me, it was a clear penalty and a clear red card because he was the last man," the City boss said.
"The sending-off was not the thing that changed the game. The game was over and completed from the beginning for our team.''
