Liverpool striker Luis Suarez has received a charge of violent conduct from the Football Association after biting Chelsea defender Branislav Ivanovic on Sunday.
The incident occurred in the second half of the 2-2 draw at Anfield as Suarez lost possession of the ball inside the Chelsea penalty area and proceeded to turn and bite Ivanovic on the arm.
No official spotted the bite, and Suarez was therefore allowed to stay on the field and eventually score the equalizing goal deep into stoppage time.
"The incident was not seen by the match officials and has therefore been retrospectively reviewed," read a statement from the FA. "It is alleged that the conduct of Suarez constitutes violent conduct and it is the FA's contention that the standard punishment of three matches that would otherwise apply is clearly insufficient in these circumstances."
Suarez has until Tuesday to respond to the charge.
The Uruguay international was suspended for seven matches in 2010 as a member of Ajax when he bit an opposing player, while he received an eight-match ban last season for racially abusing Manchester United's Patrice Evra.
Suarez has tallied 23 goals for the Reds in the league this season, but with just four matches left in the campaign, it is likely that he will be facing a lengthy ban that carries beyond this season.
