UEFA announced today AC Milan midfielder Gennaro Gattuso has been charged with "gross unsporting conduct" after headbutting Tottenham coach Joe Jordan following Tuesday's Champions League clash at the San Siro.
UEFA's control and disciplinary body will discuss the case against the 33-year-old Italian on February 21.
Gattuso clashed with Jordan during Spurs' 1-0 win then confronted the former Scotland international at full-time.
Former Rangers midfielder Gattuso, who was booked during the match and also clashed repeatedly with Tottenham striker Peter Crouch, headbutted Jordan before being led away.
Gattuso's caution - awarded for a rash challenge on Steven Pienaar after which the Italian repeatedly hit the turf in anger - ensures the 33-year-old will be suspended for the return leg at White Hart Lane on March 9.
That ban is certain to be extended when UEFA's control and disciplinary body meet on Monday to discuss the case.
UEFA rules stipulate a minimum three-match ban for assault, although the governing body have the power to dole out lengthier suspensions in exceptional cases.
Gattuso's agent Claudio Pasqualin has since stated that Jordan had used provocative language towards the midfielder prior to their clash. Spurs have declined to comment on his claims.
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."
