Watford striker Troy Deeney is facing a stint on the sidelines for a controversial goal celebration against Chelsea.
Deeney scored one of four Watford goals as pressure mounted on Chelsea manager Antonio Conte following the 4-1 thrashing.
After Deeney slotted home the first goal of the game via a penalty, the striker flipped the middle finger at Chelsea fans.
If precedent is anything to go by, he could be in for a ban.
Dele Alli was banned for one international game after using the middle finger in England’s World Cup qualifier with Slovakia last year.
Daryl Janmaat, Gerard Deulofeu and Roberto Pereyra all scored late on in response to Eden Hazard dragging Chelsea back into the game with a superb equaliser in the 82nd minute.
Tiemoue Bakayoko was sent off for a second booking on the half-hour before Deeney gave the Hornets the lead at halftime.
Deeney made no mistake from the penalty spot after Chelsea goalkeeper Thibaut Courtois was adjudged to have brought down on-loan Barcelona winger Gerard Deulofeu.
"Obviously the penalty is a clear dive," Courtois told Sky Sports.
"If a striker just puts his feet there and that's a penalty then I think we're not far away from everything being a penalty, he clearly leaves his foot and he dives."
