MILWAUKEE -- Brewers right fielder Gabe Kapler has a torn muscle in his right shoulder and could miss the rest of the season.
Kapler will stay in Milwaukee and undergo physical therapy with the team in an effort to determine whether he can return this year.
The team said Thursday that Kapler is hopeful he can return this year but gave no timetable for his recovery.
He left Wednesday's game after making a hard throw to the plate in the sixth inning against the Cincinnati Reds.
With the Reds leading 3-1, Kapler's throw kept Edwin Encarnacion from attempting to score on Jay Bruce's single, but Kapler, in the lineup for struggling All-Star Corey Hart, immediately winced in pain and grabbed for his shoulder.
Milwaukee went on to rally for a 4-3 win, thanks in part to Kapler's effort.
Kapler, who retired from baseball for a year because of injuries and became a manager, is hitting .301 with eight homers and 38 RBIs in 229 at-bats this season after signing as a free agent with the Brewers.
