The diagnosis was made by Astros team medical director Dr. David Lintner, and Backe will seek a second opinion Monday in Birmingham, Ala., from renowned orthopedic surgeon Dr. James Andrews. The Astros would have to pay for any surgical procedures as long as Backe remains a free agent.
Backe, 31, began the 2009 season on the disabled with a strained left intercostal muscle, an injury he sustained during a Spring Training start on March 8 against Pittsburgh. Backe was reinstated from the DL on May 28 and made five appearances for the Astros with one start, posting a 0-0 record with a 10.38 ERA.
Backe was designated for assignment after allowing 15 runs and 21 hits in 13 innings (one start) for the Astros this year. He's 31-29 lifetime with a 5.23 career ERA but endeared himself to Astros fans by coming up with big starts in the playoffs in 2004 and 2005.
