The FA will investigate the clash between Arsenal team-mates Emmanuel Adebayor and Nicklas Bendtner during their Carling Cup semi-final thrashing at Spurs.
Match referee Howard Webb took no action during the game at White Hart Lane, but the FA have asked to television footage of the incident, which is reported to have been started by a headbutt by Adebayor.
Gunners skipper William Gallas helped to separate the two players involved, aided by Croatian striker Eduardo, with Webb's match report stating he did not see the actual fracas.
Gallas said after the game: "I don't know exactly what happened. I think everybody was disappointed with the score and they were nervous.
"They know they made a mistake and maybe they will have to go to the boss and explain why they did that. They are young and they have to understand that.
"We lost our calm. Sometimes it is difficult to be calm and it is not easy for some players to be calm. We were too nervous. We have to learn."
