The Liverpool striker could be banned for at least three matches if football’s governing body finds him guilty of violent conduct.
Liverpool’s Luis Suarez has been charged with violent conduct by the FA after biting an opponent during a Premier League clash.
Television footage seen by millions of people showed the striker sinking his teeth into Chelsea’s Branislav Ivanovich.
He apologised for what he called his “unacceptable behaviour” and has already been fined by his club.
However, he could now be banned for a number of matches if football’s governing body rules the bite constitutes violent conduct.
A spokesman for the FA said: “It is our contention that the standard punishment of three matches that would otherwise apply is clearly insufficient in these circumstances.”
The incident, which happened during the 2-2 draw at Anfield, was “retrospectively reviewed” by the FA because it was missed by match officials.
Suarez has until 6pm tomorrow to respond to the charge, with an independent regulatory commission expected to meet on Wednesday to decide whether he should be punished.
Liverpool have only four games left this season and a match ban of the length sought by the FA would bring his season to a premature end.
The club has so far stood by Suarez, although managing director Ian Ayre has said the 26-year-old will need to work on his discipline.
Liverpool manager Brendan Rogers added: “His behaviour is unacceptable and I have made him aware of this.”
Suarez has asked the club to donate his fine to the Hillsborough Family Support Group, which was set up in the wake of the 1989 disaster in which 96 people died.
The Uruguayan international will also be offered anger management counselling, the Professional Footballers’ Association said.
Suarez has been charged with biting another player once before.
He served a seven-match ban in the Netherlands while at Ajax after biting PSV Eindhoven midfielder Otman Bakkal.
