Right-handed reliever Matt Lindstrom, who exited Friday’s game in the eighth inning after a liner by Johnny Damon struck bone on the inside of his left knee, left the club briefly Saturday afternoon to have an X-Ray.

Showalter called it “precautionary.” Lindstrom said the swelling had subsided some after four ice treatments, but he was still in pain Saturday afternoon.

“It is pretty sore. It caught me pretty square. I’m not going to know too much until we get the swelling out,” Lindstrom said. “It got my bone. It didn’t get knee cap or anything like that, but I have swelling in the back of my knee.”

He is unavailable Saturday but is hoping he is sidelined only a few days.
