Walcott made the gesture as he was being carried off on a stretcher during the Gunners' FA Cup victory over their arch-rivals at the Emirates Stadium last weekend, having been pelted by coins and plastic bottles, among other objects, from the away end.

The England forward jarred his knee and the injury has since been subject to specialist assessment, although its not yet known how long he will be out of action.

But the possibility of disciplinary action was removed by the Football Association (FA), the English game's governing body, on Monday.

"The FA has contacted both Arsenal and Tottenham Hotspur to seek their observations in relation to objects being thrown from both a home and away section of the crowd at different times during Saturday's FA Cup third round tie.

"The FA condemns any such acts and will liaise with both clubs and the Metropolitan Police to identify those responsible and support the strongest sanctions available, including life bans.

"Meanwhile, in relation to the same fixture, The FA has contacted Arsenal's Theo Walcott and reminded him of his responsibilities regarding a 'score-line' gesture he made in front of away supporters during the game. The FA will not be taking any further disciplinary action."
