ROME — Juventus and AC Milan each played to scoreless draws Sunday as the top of Serie A remained unchanged, but Milan standout Zlatan Ibrahimovic was sent off for punching an opponent and could face a multi-game ban.
In the 64th minute of Milan's match with Napoli, Ibrahimovic landed a right hook into defender Salvatore Aronica's head.
Ibrahimovic will miss a difficult game at Udinese next weekend and, if he is suspended for up to three matches, will also miss a match with Juventus on Feb. 25.
Juventus, which was held 0-0 at home by Siena, leads Milan by one point and has a game in hand.
Also Sunday, Roma routed Inter Milan 4-0 in a match postponed by 24 hours due to a rare snowstorm in the capital.
