Junk is no longer scheduled to start Sunday's game against the Mets and could be headed for the injured list, Christina De Nicola of MLB.com reports.
The Marlins haven't provided any details regarding what kind of issue Junk is dealing with, but he doesn't look like he'll be available out of the bullpen once opening pitcher John King exits the game Sunday. Junk has made 11 starts this season while posting a 3-5 record with a 4.80 ERA, 1.30 WHIP and 43:13 K:BB in 60 innings.
