The Tottenham star has been charged by the FA for alleged violent conduct.
Tottenham's 1-1 draw at home to West Brom in the middle of the title race could be compounded by a forthcoming ban to one of its key players.
Video replay shows PFA Young Player of the Year Dele Alli appearing to punch Claudio Yacob in the stomach/hip area during an off-the-ball incident in Monday's match at White Hart Lane. The 20-year-old rising star could face an FA charge and disciplinary fallout for his actions, which did not merit a card from referee Robert Madley.
The incident, which can be seen below, comes at an opportune time for Tottenham, which must rebound while hoping Leicester City slips up in a big way in its final three matches. The Foxes can clinch the trophy with any combination of three points.
Alli is Tottenham's second-leading scorer behind Harry Kane, with 10 goals on the season.
