Veteran forward Filippo Inzaghi will be out for two to three weeks with a hamstring strain, his club AC Milan said today. The 38-year-old has been a bit-part player this season, making just eight appearances in all competitions. All of those, bar one, was as a substitute. The injury comes at an inopportune time for Inzaghi, who may have been in line for more regular first team action with Pato out injured, Antonio Cassano\'s long-term heart problem and doubts over both Robinho and Zlatan Ibrahimovic. It means only Argentine Maxi Lopez and youngster Stephan El Shaarawy are definitely fit for this weekend\'s game against Roma, although Ibrahimovic is expected to overcome a back problem.
