Tottenham midfielder Dele Alli could face retrospective action from the FA after he was filmed hitting out at West Brom's Claudio Yacob off the ball during the 1-1 draw on Monday Night Football.
The 20-year-old, who was awarded PFA Young Player of the Year on Sunday, appeared to deliberately punch Yacob in the stomach as the pair clashed in the West Brom penalty area in the first half.
Standard procedure for retrospective action for violent conduct is a three-match ban, which would put Alli out of action for the rest of the season.
Spurs' title hopes faded strongly after they dropped two points at White Hart Lane, a result which left Leicester seven points clear at the Premier League summit and one victory away from the title with three games remaining.
Tottenham head coach Mauricio Pochettino admitted after the game that he was aware of the Alli-Yacob incident but did not see it.
He told Sky Sports: "I didn't see. I heard some comments. I need to watch the game and the action, so I cannot say nothing."
Commenting on the incident on Monday Night Football, Jamie Carragher said: "He's been involved in these things before.
"Claudio Yacob's job appeared to be to get at Alli, and there was an incident before with a few words said."
Tottenham's next match is away to Chelsea on Monday Night Football next week before their penultimate game of the season at home to Southampton on May 8. They travel Newcastle on the last day of the season on May 15.
