Barcelona striker Samuel Eto'o has been ruled out for at least two months with a thigh injury picked up against Inter Milan on Wednesday in a friendly game. Doctors estimate the injury would keep him out for two months but they haven't decided yet if the Cameroonian striker needs a surgery or not. The 26-year-old suffered the injury just two minutes after coming on as a substitute in Wednesday's 5-0 victory over Italian champions Inter Milan in the Gamper Trophy at the Nou Camp. The Barca number 9 had already missed a big part of the previous campaign as he suffered from a knee injury that sidelined him for almost six months. The injury will allow new signing Thierry Henry to take his place as a regular starter in Frank Rijkaard's lineup.
