Chelsea top four hopes face a big blow.
Branislav Ivanovic is facing a three-game punching ban - but not until after he plays at Fulham tonight.
Video footage clearly shows the Serbian defended swinging a left fist into the face of Wigan's Shaun Maloney just before Juan Mata's controversial winner for Chelsea on Saturday.
FA disciplinary chiefs have been alerted to the footage and will review the video today before asking ref Mike Jones to confirm he did not witness what happened.
