Leicester City striker Jamie Vardy has been charged with improper conduct for his behaviour following his second-half dismissal against West Ham on Sunday, the Football Association has announced.

Vardy was dismissed in the 56th minute of the 2-2 draw against West Ham after referee Jon Moss adjudged the striker to have dived under a challenge in the box from Angelo Ogbonna.

The England international reacted furiously, pointing and shouting in the face of the official before eventually leaving the pitch.

From the red card, Vardy is currently due to serve a one-match ban, which rules him out of Sunday's home game against Swansea City. But the FA's charge means he could miss the trip to Manchester United on May 1 as well.

The FA also charged Leicester for failing to control their players following the awarding of an 83rd-minute penalty to West Ham.

Vardy and Leicester will have until Thursday evening to appeal.

In a similar case this month, Chelsea striker Diego Costa was given a one-match suspension, fined £20,000 and warned as to his future conduct after he protested angrily to referee Michael Oliver rather than leaving the pitch immediately after seeing red at Everton.

Former Premier League referee Howard Webb does not believe Vardy has a clear case to answer.

"The FA will look at whether to punish Vardy further for berating Moss," Webb wrote in his column for the Times. "They extended Diego Costa's ban recently for his aggression towards Michael Oliver but Vardy might be saved by the fact he left the field fairly quickly.

"Screaming at the referee like that wouldn't happen if this was a Champions League game, as Leicester face next season. Refereeing as a foreign official was always easier as players didn't know you well so feared and respected you more."

The FA are also still studying comments from West Ham's Andy Carroll after the forward hit out at Moss following his decision to award Leicester a stoppage-time penalty.
