Rockies' Ryan Feltner: Placed on IL due to back spasms

The Rockies placed Feltner (back) on the 15-day injured list Friday, retroactive to April 29.

Feltner had his last start pushed from Sunday to Monday against Atlanta due to a back issue. He took the loss in that outing after allowing five runs on a season-high 10 hits. He's eligible to be activated off the IL on May 14, but he'll undergo further tests to establish a concrete timeline for his return. The Rockies recalled Bradley Blalock from Triple-A Albuquerque in a corresponding move.
