The Chelsea defender Frank Leboeuf could be in more trouble with the Football Association following his stamp on Leeds United's Harry Kewell on Sunday.

But fellow French star Emmanuel Petit looks set to escape punishment for allegedly spitting towards Wimbledon striker John Hartson in Saturday's Premiership clash at Highbury.

Leboeuf was dismissed for two bookable offences on Kewell within seven second-half minutes in a bad tempered clash at Stamford Bridge which Leeds won 2-0 to reclaim top spot in the league.

The Frenchman then appeared to stamp on the Australian's foot as he lay on the ground and could now face a lengthy ban after referee Jeff Winter confirmed he would be making a report of the 68th minute incident to the FA.

"I did notice the stamp and that will be the subject of a supplementary report to the FA," said Winter. "Leboeuf was dismissed for the second bookable offence but what happened afterwards will be the subject of a separate report."

Leboeuf would have faced at least a two-match ban anyway as it was his second dismissal of the season following a red card at Everton last month.

But he can now expect a longer suspension if the FA decides to act on Winter's report, which could also include the fact that Leboeuf remained on the pitch to argue his case and then continued the argument with Leeds officials on the bench before eventually walking down the tunnel.

Meanwhile, Petit appears to have been more fortunate with referee Graham Barber not noticing the alleged spitting incident in Arsenal's 1-1 draw with Wimbledon.

"If I had seen something I would have taken action at the time," said Barber. "Both players were booked in the 89th minute but I understand that the alleged incident took place earlier in the game."

That would seem to mean an end to the matter with Welsh international Hartson himself not aware of the incident until after the game and unlikely to lodge an official complaint.
