Big changes are afoot at ABC's "Body of Proof."

TVLine was the first to report thatJohn Carroll Lynch is leaving the ABC medical drama to join "Do No Harm."

Lynch, who played homicide detective Bud Morris in the first two seasons of "Body of Proof," guest starred in the pilot for the NBC crime drama. In "Do No Harm," he had a brief scene as the NA sponsor of protagonist Dr. Jason Cole -- and his alter ego Ian Price -- played by "Rescue Me's" Steven Pasquale.

But Lynch is not the only one moving on from "Body of Proof." According to The Hollywood Reporter, Nicholas Bishop, who played medico-legal investigator Peter Dunlop on the series' first two season, is also leaving "Body of Proof" behind.

In the Season 2 finale, Bishop's character was last seen bleeding after getting stabbed during a fight, while viewers left Lynch's Bud Morris celebrating at a baby shower with his wife.
