Leicester City have been fined £17,250 for fan violence that ended their Europa League tie with Napoli.
Supporters from both sides clashed at the end of the 2-2 draw with a series of missiles.
UEFA charged Fox with two counts of ‘crowding’ and ‘throwing objects’ and has now confirmed the fines.
Napoli, who faced the same two charges as well as ‘damaging’ the King Power Stadium, were fined just under £13,000.
A dozen fans were arrested after the match on 16 September.
About 100 police and stewards ran to the far corner of the field, where 250 Napoli fans were placed as bottles were launched shortly after the full-time whistle.
And there were ugly scenes as baton-powered police rose to separate rival fans as clashes broke out and stewards struggled to restore order.
An appeal on the speaker system called on supporters to ‘respect their club’ by ‘stepping away from the line of separation’.

However, trouble escalated for a few minutes before the police restored some level of order.
It came as Leicester fans erased a two-goal lead from Victor Osimhene’s second-half strike, with the Napoli striker snatching a draw three minutes from the end.
At the final whistle, a small band of Napoli audiences appeared to taunt their Leicester counterparts before the mood took a frighteningly sinister turn.
Followers of the foxes climbed onto the cover of the tarpaulin and the stewards were overwhelmed when the punches were thrown.
Some Italians were seen removing their belts which they used as weapons to attack rivals.
UEFA also confirmed that Aaron Wan-Bissaka should serve a two-game Champions League ban for his red card in a loss to the Young Boys.
Meanwhile, Spurs were warned over the gloves worn by keeper Pierluigi Golini in the conference league draw in Rennes, which violated UEFA rules on the shape of the logo.
