Kind of a misleading headline because I don't have one, but I do know that relief pitcher Cristhian Martinez has been called up to the Atlanta Braves from triple-A Gwinnett. Presumably he will take the roster spot of Medlen, at least until Monday when a decision is made on who will be taking Medlen's spot in the rotation.
This means they are definitely putting Medlen on the disable list. I don't expect Martinez to be in the rotation, but the team might as well call up a fresh bullpen arm they can use while they make a decision on who should start Monday.
This post will be updated when more info about Medlen is made available.
