Tevez had to be substituted in Thursday's 2-0 loss to Mexico's Tigres after injuring his right knee in a challenge with a defender.

Initial examinations conducted after the team arrived in Brazil on Friday showed the striker will likely be out for at least two weeks.

Tevez, a regular on the Argentina national team, will miss Sunday's match against rival Sao Paulo and at least one other match in the Sao Paulo state championship. He is not likely to play in the team's next Copa Libertadores match, against Tigres again, on March 22.

The Argentine, who scored six goals in nine matches this season, was Corinthians' top acquisition last year. He led the club to its fourth Brazilian league title and was named the competition's best player.

Corinthians is fourth in the 20-team Sao Paulo state championship with 25 points from 13 matches. Santos leads the tournament with 31 points, five more than Sao Paulo and Palmeiras.
