AC Milan midfielder Gennaro Gattuso could face a lengthy ban after UEFA today announced it has opened disciplinary proceedings following his clash with Tottenham coach Joe Jordan.
Gattuso headbutted Jordan after the fiery Champions League match between the two sides at the San Siro. The game finished 1-0 to the Premier League side thanks to a Peter Crouch goal in the 80th minute.
UEFA's Control and Disciplinary Body will meet next Monday to discuss the case.
Tottenham's victory in the last-16 encounter was overshadowed by Gattuso's antics, with the former Rangers midfielder involved in several incidents.
Gattuso clashed with Crouch during the match and also squared up to Jordan and pushed him in the face on the touchline during a frenetic second half.
His headbutt on Jordan after the final whistle sparked angry scenes, with several players from both sides involved in the ensuing melee.
Gattuso later apologised for his actions, saying: "I lost control. There is no excuse for what I did. I take my responsibilities for that.
"I was nervous. I didn't want to argue with players and I did it with him, but I was wrong to do what I have done."
The ill-tempered encounter was also marred by Matthieu Flamini's ugly two-footed challenge on Vedran Corluka which left the Spurs full-back with an ankle injury.
The former Arsenal player was booked at the time, however, and is therefore unlikely to face any further punishment.
