McClanahan (back) said Friday that he expects to miss just one start and be on the injured list for the minimum 10 days, Neil Solondz of the Rays Radio Network reports.
McClanahan moved to the injured list with back stiffness earlier Friday, but all indications thus far are that he will return to the rotation after missing just one start. He becomes eligible to come off the IL on Sept. 19 against the Tigers, though it's possible the club waits to activate him until the following series against the Blue Jays.
