"He felt it on the second-to-last pitch of the outing," Rays manager Kevin Cash said. "We're hopeful that it's not something that's too bad. But we're going to let our doctors get their hands on him. Look at it, and we'll go from there. All I know is he's on a plane and he's going to see the doctor tomorrow morning."
Cash said he did not notice anything off when McGee was on the field.
"He talked to the trainers once he got into the dugout," said Cash. "[The injury] definitely happened last night."
Cash did not totally dismiss the idea that McGee could join the team in Oakland for the three-game weekend series against the A's.
