The French midfielder has been a regular fixture in the north London side’s first team in recent weeks following Francis Coquelin’s spell on the sidelines with a knee problem.
However, Flamini was left out of the Arsenal side who beat Bournemouth to move back to the top of the Premier League table on Monday night.
Speaking after the game at his post-match news conference, Wenger confirmed Flamini’s ankle problem, and said that Kieran Gibbs was substituted late on due to cramp.
Wenger said: “He [Flamini] might be alright. I could have pushed him but he was a little risk so I decided not to take it because it was an inflamed ankle. Gibbs is cramp on his calf.”
Arsenal took the lead in the 27th minute when Gabriel Paulista headed home Mesut Ozil’s corner.
Ozil was in sublime form throughout the game and made it 2-0 when he exchanged passes with Olivier Giroud and slotted home in the 63rd minute to wrap up victory for Wenger’s men.
Arsenal host Newcastle on Saturday in their next top-flight game.
