TR Knight's not the only Grey's Anatomy star grabbing headlines this week. Rumor has it Isaiah Washington will not be returning to the hit ABC series. At least not on a regular basis.

Us quotes a proverbial insider: “He will not be back as a series regular". The actor - whose faggot flinging led Knight to come out of the closet - may appear in a few episodes. The article also claims that Knight didn't earn many friends during his two season stay on the set.

Katherine Heigl, 28, said her costar “just needs to stop talking” after Washington used the f-word again at the January 15 Golden Globes, but the damage had been done.

“The cast – especially the women – just don’t like him,” says a Grey’s source.

“The stars of the show really felt ABC made a mistake by keeping Isaiah [after his controversial behavior].”

Washington's flacks deny the rumors and claimsthe actor's still a part of the Grey's team. The representative does concede, however, that they have yet to receive a contract.

We're on the edge of our seats!!! Okay, not really, but we bet Washigton's shitting bricks...
