MILAN, ITALY - Inter Milan goalkeeper Julio Cesar suffered a thigh injury Wednesday, and the Italian club could be without its best goalie for up to a month.

Cesar suffered a second-degree strain in his left thigh and, although there was no exact timetable on his injury, he could miss Serie A matches against Juventus, Genoa and Cagliari, as well as two Champions League fixtures.

The 32-year-old Brazilian was replaced at halftime of Wednesday's 1-1 draw at Atlanta, and Luca Castellazzi came on to save a penalty kick in the fixture.

Castellazzi will likely step into the starting role, as Inter looks to climb up the standings. Inter is currently 16th with just eight points from eight matches.
