The Rangers have scratched Roy Oswalt from his scheduled start Monday because of stiffness in his back, and Colby Lewis will have his forearm examined by Dr. Keith Meister on Monday before the Rangers decide if he can start Tuesday.
That seems unlikely, though the Rangers still have him listed as their starter against Boston. Martin Perez would likely be the choice in Lewis can't go. Oswalt, who is in Houston for an exam, will be replaced by Scott Feldman in the opener of a three-game series at Rangers Ballpark.
The Rangers do not believe Oswalt's injury is serious, though both he and Lewis could wind up on the disabled list. Oswalt felt discomfort on the last pitch of his bullpen session Friday.
Oswalt has had back problems the past few seasons, and the health of his back was a concern as he went unsigned through the free-agent period over the winter and didn't sign on with a club until the Rangers agreed with him in May in light of an elbow injury to Neftali Feliz.
Lewis went on the disabled list with forearm tendinitis June 26 and was reinstated Wednesday for a start at Oakland. He allowed one run in five innings but left as a precaution after he felt tightness. He was scheduled to throw a bullpen session Saturday but did not.
