Noah Trister of the Associated Press reports that Tigers outfielder Brennan Boesch tweaked a right oblique muscle on Saturday while swinging a bat.
He was held out of workouts on Sunday and might not be ready for action again until later this week.
Boesch agreed to a one-year, $2.3 million contract with the Tigers back in mid-January, avoiding salary arbitration, but he is not locked into a starting job for the 2013 season and can’t do much to change that.
The 27-year-old batted just .240/.286/.372 in 503 plate appearances last summer for Detroit and will serve as a reserve this year behind starting left fielder Andy Dirks, starting center fielder Austin Jackson and starting right fielder Torii Hunter.
The oblique injury should be a non-issue by the opening of the Grapefruit League schedule.
