The Detroit Tigers, having endured their share of injuries on the young baseball season, will be crossing their fingers this week.

Designated hitter Gary Sheffield, who sat out Sunday's game against the Blue Jays, will have his surgically-repaired right shoulder examined once the team returns from a four-game series in Toronto.

Sheffield had surgery last October to repair a tear in his shoulder. The slugger also had surgery on the same shoulder in 1995.

Sheffield believes scar tissue from the surgery is limiting his range of motion.

"I want to get it looked at," Sheffield said, adding he might have returned to the lineup too quickly. "I want to make sure I know what's going on, how much scar tissue I really need to break up.

"When you have surgery you're supposed to break up all the scar tissue to be normal and I never got that opportunity. I had surgery in November, I was in a splint until the end of December and I was on the baseball field in February."

Sheffield added he can't throw a baseball and has difficulty reaching across his body.

He is batting .192 in 52 at-bats this season with one home run and two runs batted in.

Sheffield played in 133 games for Detroit last season, but missed the first week of August with soreness in his shoulder and later spent two weeks on the disabled list.

Signed through 2009, Sheffield will earn $28 million US over the next two seasons.

Second baseman Placido Polanco (stiff back) also sat out Sunday for the third time in the past four games. He is batting .148 with four RBI in 54 at-bats.

Also sidelined for Detroit is pitcher Dontrelle Willis (knee), outfielder Curtis Granderson (broken right hand) and relief pitchers Fernando Rodney (shoulder tendinitis) and Joel Zumaya (shoulder surgery).

Regular first baseman Carlos Guillen was the designated hitter for the Tigers on Sunday, while Ryan Raburn made his second straight start in place of Polanco. Miguel Cabrera moved to first base and Brandon Inge got the start at third.
