AC Milan's Serie A challenge has been hit by the news that defender Alessandro Nesta will be sidelined for three weeks after dislocating his shoulder.

Nesta suffered the injury during Sunday's 2-0 win over Cesena that ensures the Rossoneri are four points clear of Napoli at the top of the Italian table.
The defender has not sustained a fracture or any ligament damage, but has been told he must undergo a period of rest by doctors.
"I believe Nesta will be out for two to three weeks and will miss six to seven games," Vice-president Adriano Galliani confirmed.
Nesta will not play in the Coppa Italia quarter-final game against Sampdoria this week and will also miss Serie A games against Catania, Lazio, Genoa and Parma.
However, it is anticipated that the experienced defender will return to Massimiliano Allegri's starting XI in time for the Champions League second round, first leg tie against Tottenham on February 15.
Milan completed a deal to sign Ajax defender Urby Emanuelson at the weekend and have been strongly linked with Genoa star Domenico Criscito as they consider making another defensive signing.
"We'll see, we'll see," Galliani said regarding further transfer activity. "There is still a week left. We'll see about not throwing the entire week away."
Meanwhile, Emanuelson has revealed how his move to Milan took him by surprise.
Emanuelson told Gazzetta dello Sport: "This is a dream come true for me. Milan is one of the best clubs in the world and I'm honoured to be here.
"Everything happened very fast as Milan only called me on Wednesday and by Saturday the deal was completed. I hope to do great things at the club. I want to give my best and help the team win titles."
