Seahawks starting center Chris Spencer, troubled by persistent shoulder problems during a recent minicamp, will not need a second surgery at this time, and will rehabilitate for the rest of this week in Birmingham, Ala., in an attempt to reduce his discomfort. After experiencing soreness last week during the minicamp, in which he did only limited work, Spencer visited earlier this week with noted orthopedic specialist Dr. James Andrews for follow-up opinion. Andrews repaired both of Spencer's shoulders in the offseason, but determined that further surgery was not indicated. Had surgery been required, Spencer likely would not have been recovered in time for the start of training camp in late July, and there were fears he might miss the entire season. Spencer's representatives said Andrews was confident that non-surgical rehabilitation will improve the condition of the two-year veteran.
