Adam Eaton will be out for up to two months because of a sprained left elbow.

Kevin Towers said Eaton had an MRI that revealed a small tear in the fibers around the ulnar collateral ligament. The Diamondbacks outfielder had been bothered by a sore elbow for a couple of weeks and the Diamondbacks had recently given him a couple days off.

"Of course you like to play through it as a competitor," Eaton said. "You don't like to be in the training room at all and get that type of attention. A couple of guys I talked to talked me in to going in and getting it checked out. I was still thinking it was nothing. I've never had any arm problems my whole life."
