Seattle Grace is losing one of its doctors.

Actor T.R. Knight, who portrays the misguided M.D. George O’Malley, is leaving Grey’s Anatomy, according to a new report.

Sources tell Entertainment Weekly columnist Michael Ausiello that ABC has released the actor from his contract with the award-winning Seattle-based medical drama after a series of spats with show creator and head writer Shonda Rhimes.

The decision was reportedly made in the last several days.

Reports first emerged in February that Knight and his real-life best friend and co-star, Emmy winner Katherine Heigl, wanted out of the series.

During the Season 5 finale of Grey’s, which aired in May, George’s life was left in limbo after the doctor was hit by a bus, shortly after signing up for the military.

T.R. Knight has starred on Grey’s since the series’ primetime introduction in 2005.
