Feyenoord have been hit with their second fine from Uefa in a week following the conduct of supporters during their recent Uefa Cup game against Blackburn.
A fan of the Rotterdam side was caught throwing beer at Morten Gamst Pedersen, who was hit by a plastic cup, while fireworks were also set off.
This latest fine of é¼12,000 (£8,100) has followed on from the é¼125,000 (£85,000) they were were forced to pay as punishment for the riots in Nancy on November 30.
Feyenoord were also informed that they may have to play two European games behind closed doors if their supporters repeat any such incidents.
The Dutch giants have been given three days to appeal this latest fine.
