Carl Crawford's "pause" has turned into a setback that might prevent him from being ready to open the season on time. The Dodgers outfielder, who is returning from Tommy John surgery on his left elbow last August, will be restricted to limited activity – no swinging or throwing – for the next seven days because of nerve irritation in his left arm related to that surgery. Crawford started feeling soreness in his left forearm after increasing his workouts Monday and taking batting practice against a minor-league pitcher. His activity was limited the next three days and he returned to Los Angeles on Thursday to be examined by Dr. Neal ElAttrache. ElAttrache diagnosed the nerve irritation, most likely caused by Crawford's attempt to increase the intensity of his workouts and said it was "not uncommon during the rehab process of Tommy John surgery." Nonetheless, the setback makes the likelihood of Crawford being ready to play left field in the season-opener April 1 even lower than it already was. "There doesn't seem to be any kind of panic," Manager Don Mattingly said. "But I have to look at this as a little bit more of a setback than we were the last few days. "I think it definitely challenges opening day." Crawford was back in camp Friday and participated in workouts in a limited fashion. He said he was relieved when Dr. ElAttrache told him the soreness was not related to the repaired ligament and was not unusual in the rehab process. Crawford admitted he was probably guilty of pushing his workouts. He had hoped to make his spring debut Thursday. He still hopes to be ready for April 1. - See more at:
