DETROIT -- The Tigers had been weighing how to fit Dontrelle Willis and Armando Galarraga into their rotation. Now, that might not be a problem anymore, because the Tigers could have a new issue among their starters.

Privacy issues prevented the club from commenting on a cbssports.com report that Jeremy Bonderman visited a doctor on Friday to have his shoulder examined. But manager Jim Leyland acknowledged that they now have multiple decisions to make in their pitching staff.

The report cited club sources saying that Bonderman was being checked for a possible circulation problem, and could go on the disabled list. The Tigers still have Bonderman listed as their starter for Sunday's game against Cleveland, but Leyland's postgame comments showed uncertainty.

"I have several decisions pending on circumstances that I don't care to discuss," Leyland said when asked about Galarraga and his rotation. "I'm not at will to discuss."

The question regarding their Monday starter appears to be answered, though no starter has officially been listed for that contest. Galarraga threw a side session in the bullpen during the ninth inning of Friday's game, and is on track to start Monday.

With Galarraga preparing for Monday's start, that would seemingly free up Willis to start Sunday if needed. Both Galarraga and Willis pitched Tuesday at Oakland in a piggyback start, with Galarraga following Willis.

Bonderman, who wasn't in the clubhouse Friday, is 3-4 with a 4.29 ERA in 12 starts this season. The velocity on his fastball has been down in several starts, though it has improved recently. He allowed three runs on 12 hits over seven innings in his most recent outing last Sunday at Seattle, striking out five while walking no one.
