Mariners third baseman Adrian Beltre may be done for the season after taking a one-hopper to the groin on Thursday.

Beltre is out indefinitely and manager Don Wakamatsu told the Seattle Times that he could need season-ending surgery for a bleeding testicle.

"It hurt pretty bad," Beltre said. "It was hurting me pretty much the whole game after that."

He doesn't wear a protective cup because he finds them uncomfortable.
