Chelsea vs Tottenham: Harry Kane faces anxious wait to find out whether he will be banned

Tottenham striker Harry Kane faces an anxious wait to see whether retrospective action will be taken by the Football Association following an apparent headbutt on Chelsea's Cesar Azpilicueta.

The England captain appeared to put his head towards the Chelsea defender after the pair clashed in the first half of Spurs' 2-0 defeat at Stamford Bridge on Wednesday.

The incident, which stemmed from Kane closing down David Luiz after Spurs had returned possession to Chelsea, was not acted upon by referee Andre Marriner at the time.

The FA are waiting to see whether Marriner includes the incident in his report, and whether he saw it or not.

If not, the FA will review and decide whether to send it to a disciplinary panel. Should Marriner report he saw the clash, or he does not include it, Kane will face no action.

In a worst-case scenario Kane could be charged with violent conduct and face a three-match ban, which would rule him out of Saturday's north London derby with Arsenal at Wembley, along with games against Southampton and Premier League leaders Liverpool.

A suspension would be a significant blow for Spurs and Kane, who only returned to the team last weekend after a six-week absence with an ankle injury.

Kane did later receive a yellow card after another tussle with Luiz in a fesity encounter.

"I think he's so competitive on the pitch," boss Mauricio Pochettino said of Kane. "We were frustrated, we want to win, we show our character.

"Things that happen that we don't know because it's impossible from outside the pitch to see what is going on inside. But that is football.

"It's not a thing we should be worried about. When you finish the game and shake hands, big hug and the game finishes and it's finished."

Pochettino is also waiting to hear from the FA over his punishment for an improper conduct charge.

The Spurs boss was sanctioned after clashing with referee Mike Dean at the end of the 2-1 loss at Burnley on Saturday.

He accepted the charge and is awaiting punishment after turning down the chance of a personal hearing.
