HOUSTON -- Houston Astros ace Roy Oswalt will visit orthopedic surgeon Dr. Andrew Dossett in Dallas on Thursday to get a second opinion on his sore back.

Oswalt (8-6, 4.12 ERA) reported discomfort in his arm after pitching five-plus innings in a no-decision against Cincinnati on Sept. 15. He's been bothered by hip and back pain for much of the season and the team said after the start that Oswalt wouldn't pitch again this season.

Also Tuesday, Wade said relief pitcher Alberto Arias will undergo arthroscopic surgery on his right knee on Wednesday. Arias (2-1, 3.35 ERA) has been on the disabled list since Aug. 24.
