Narveson (blister) may be replaced in the rotation by Jarred Cosart on Sunday against the Mets, Joe Frisaro of MLB.com reports.

EDGE Analysis

Narveson tossed 5.1 scoreless innings against the Braves on Monday in his second start of the season, but he also suffered a blister on his left middle finger during the game. Even if the blister doesn't hold him back, there's no guarantee he sticks in the rotation.
