The Rockies placed Gilbreath on the 15-day injured list Sunday with a left elbow flexor strain.
Gilbreath presumably picked up the injury following his most recent relief appearance Friday against the Mets. Colorado reinstated Alex Colome (elbow) from the 15-day IL in a corresponding move, and he'll replace Gilbreath in the bullpen. Gilbreath has been a key part of the bridge to closer Daniel Bard with 12 holds on the season, but his ratios (4.19 ERA, 1.47 WHIP and 12.3 K-BB%) haven't been strong enough to keep him on the radar in the majority of fantasy leagues. According to Patrick Saunders of The Denver Post, Gilbreath will undergo an MRI on Monday, which should reveal the extent of his injury while also shedding light on whether surgery will be necessary.
