CLEVELAND -- Add Victor Martinez to the Indians' ever-growing list of the walking wounded.

Actually, Martinez wasn't walking. He was limping after fouling a 3-2 fastball off his left knee during his first-inning at-bat against former teammate CC Sabathia in Saturday night's game against the Yankees at Progressive Field.

After several minutes spent conferring with manager Eric Wedge and head athletic trainer Lonnie Soloff, Martinez finished the at-bat. He grounded out to second and could barely get down the first-base line. He was replaced by backup catcher Kelly Shoppach when the Tribe took the field for the second inning.

The Indians announced that Martinez suffered a left knee contusion. He was taken to nearby Lutheran Hospital, where X-rays came up negative.

Martinez was not available for comment. Wedge did not indicate that the Indians are considering a roster move to bring in another backup catcher.

"We're probably looking at [Martinez] being day-to-day for a short period of time," Wedge said.

The Indians are already hampered by Grady Sizemore's sore left elbow, which is limiting him to designated-hitting duties. They also have six players on the disabled list, including regular DH Travis Hafner.

Martinez has been the Tribe's most reliable hitter all season, batting .350 with 15 doubles, a triple, seven homers and 36 RBIs. He has, however, slowed considerably of late, with just three hits in his past 32 at-bats.
