Manchester City striker Emmanuel Adebayor has been banned for three games for violent conduct during last weekend's 4-2 victory over former club Arsenal.
Adebayor has been punished by the Football Association for stamping on former Gunners team-mate Robin van Persie, while he may face further action for charging towards the visiting fans at Eastlands after finding the net.
The Togo international will now miss the games against Manchester United, Fulham and West Ham United.
However, the furore is set to rumble on after Arsenal captain Cesc Fabregas said that he thought Adebayor should have been sent off for a rash challenge on him during the match.

Manchester United midfielder Ji-Sung Park is hoping to win even more silverware with the club after signing a new two-year contract that will keep him at Old Trafford until at least June 2012.

In cricket, captain Andrew Strauss has accepted that England's performances in the one-day series against Australia have been far from good enough.

The tourists are the overwhelming online favourites to win the seventh match in the series at Durham's Riverside ground on Sunday.
Meanwhile, Kent's director of cricket Graham Ford has paid tribute to his side after they wrapped up the County Championship Division Two title.
