Manchester United striker Romelu Lukaku is potentially facing a three-game ban after footage captured him kicking out at Brighton and Hove Albion's Gaetan Bong.
During United's 1-0 win over the visitors on Saturday (25 November), Lukaku kicked out at Bong twice during a corner that led to Ashley Young's deflected strike, giving the home side the lead in the 66th minute.
The incident was unpunished during the scramble, however, it was caught on camera and according to ESPN FC, the FA are set to review video footage of the incident.
If found guilty, the 24-year-old could be charged with violent conduct which would rule him out of United's next three league games.
The first would be an away trip to Watford on Tuesday (26 November) before two crucial meetings with Arsenal and Manchester City that could shape how the rest of manager Jose Mourinho's league campaign goes.
However, the FA can only charge Lukaku if referee Neil Swarbrick did not spot the incident.
Swarbrick was in charge of Saturday's game and is due to submit his match report on Monday (27 November), whereby if he did not spot and note the incident, only then can the FA charge the Belgian striker.
Should that occur, the Red Devils will be suffering a major blow as despite scoring just one goal in his last 10 games, Lukaku has been the main source of firepower for United this season with 12 goals in 20 appearances in all competitions.
Mourinho will likely turn to last season's top scorer Zlatan Ibrahimovic as a result, with the Swede only recently returning from a long-term injury, having made three substitute appearances.
