Injury Could Keep Rolen Out Six Weeks

St. Louis Cardinal third baseman Scott Rolen was put on the 15-day disabled list Thursday because of a sprained left shoulder and could sit out up to six weeks.

Rolen’s shoulder was still too sore to undergo complete medical testing, but George Paletta, the team physician, said the results of an MRI exam showed no significant structural damage and he was hopeful Rolen would be able to take a second exam today that would detect any damage to the labrum. Rolen was injured in a collision with the Dodgers’ Hee-Seop Choi on Tuesday.
