Detroit Tigers catcher Alex Avila was put on the 15-day disabled list Saturday because of a knee issue.
The team also said that David Price has a mild strain of his right hamstring and a decision will be made early next week about when the left-hander will make his next start.
The Tigers described Avila's injury as a "loose body." He could need arthroscopic surgery.
"Normally it's like a piece of bone or something like that," he said. "It affects me getting out of a chair. It's been pretty painful for a while, for the past few weeks. Some days it's been difficult just to walk around and stuff like that, so I knew it was probably something a little more serious, and basically I've been playing with it."
Avila is hitting .200 with two home runs and eight runs batted in.
"We don't know any type of timetable really," Avila said. "We're trying to basically figure out the course of action right now. But my expectation and my hope would be to be back and ready to go, good as new, for the second half. That would be my hope and I think that's a pretty realistic possibility."
Price was injured Friday night against Kansas City when he stepped on a bat that had been tossed aside by the plate umpire in anticipation of a play at home.
Price is 3-1 with a 3.30 earned-run average. He said Saturday he was feeling fine.
"It's just when things happen to you that never happened before, it's just scary," he said.
