Rockies' Ryan Rolison: Back on injured list

Rolison has been on the 7-day injured list at Triple-A Albuquerque since June 4 due to an unspecified issue.

While recovering from shoulder surgery he underwent last summer, Rolison opened the season on the Rockies' 60-day IL and didn't begin a rehab assignment in the minors until mid-May. He was ultimately optioned to Albuquerque after being reinstated from the IL, but he made just four total appearances for the Triple-A affiliate before landing back on the shelf. It's unclear if Rolison suffered a setback with his surgically repaired shoulder or if he's dealing with an unrelated issue.
