South Carolina coach Ray Tanner told reporters Tuesday that All-America center fielder Jackie Bradley Jr. has a torn tendon in his left wrist and is "unlikely" to return this season.

"Jackie, I think, may end up having surgery, and I’m speculating right now," Tanner said. "There’s some dialogue going on right now about that. It’s unlikely Jackie will be back. It’s unlikely he’s going to be back without surgery. It’s a tendon issue that’s going to take some time."

Bradley, a potential first-round pick this June, injured his wrist diving for a ball in the outfield in the fifth inning Saturday at Mississippi State. Though a prolonged slump has dropped his batting average to .259, he is South Carolina's best all-around player and will not be easily replaced. Bradley was the Most Outstanding Player of the 2010 College World Series, where he led the Gamecocks to their first national title. It looks like the second-ranked Gamecocks will have to defend their title without him.

Tanner did reveal a bit of good news, however. Sophomore outfielder Evan Marzilli could be activated as early as this weekend, Tanner said. Marzilli has been out with an undisclosed medical condition.
