Shoulder tendinitis delays Marshall's rehab

CINCINNATI -- Reds left-handed reliever Sean Marshall, who has been on the disabled list since May 24 with a sprained left shoulder, has had a setback in his throwing program. Marshall last threw in the bullpen on Sunday in Atlanta and was slated to throw to Reds hitters during Thursday's post-All-Star Game workout.

"At the end of the bullpen, he was a little tender," Reds head trainer Paul Lessard said on Friday. "After treatments at the end of the day, he was feeling OK. Yesterday, we were planning on starting our workout with that live BP session, and while he was long tossing and warming up, he was still feeling some tenderness in the back of the shoulder. We shut it down."

A medical exam on Friday confirmed that Marshall had shoulder tendinitis.

"Thank God there is nothing else involved. We shut down the throwing program through this weekend," Lessard said. "We'll see how he responds. If he does well, he will resume his throwing program probably on Monday."

If Marshall is able to return to throwing soon, he is expected to pick up where he left off in his program.
