Rains, 42, will not be returning to the medical drama as a series regular, Deadline reported on Friday, June 28. The actor's exit comes after the fate of his character, ER surgeon Dr. Crockett Marcel, was left up in the air after the season 9 finale.

And what that is, I haven’t yet figured out — but it’s something.”
