ST. PETERSBURG, Fla. -- Chicago White Sox right-hander Jake Peavy was removed from his rehab outing with Double-A Birmingham on Monday after just two-thirds of an inning after experiencing some discomfort.
Peavy will be re-evaluated on Tuesday.
"[More] bad news for the White Sox," manager Ozzie Guillen said. "It's something I worry about because he's my player and that's a setback for him. Hopefully tomorrow we have better news. I think he's going to see the doctor.
"In my mind, I know it was going to happen. If it happens in July, [it's worse]. Of course, we want him here but we have to wait and be patient with him."
Peavy was getting hit hard in the early going against Mississippi. He gave up three early runs on four hits while throwing just 15 pitches.
Out since last July because of a detached latissimus dorsi muscle, Peavy has been rehabbing that injury as well as rotator cuff tendonitis that developed during spring training.
He is supposed to make one more rehab start before rejoining the White Sox pitching staff in late April, but that schedule is now in question.
