Is TR Knight Returning to Seattle Grace?

TR Knight got rid of the red hair by the time he cohosted the 52nd annual OBIE awards which honors achievements in the off-Broadway stage. That was fast although apparently he wants to keep playing with his hairstyles. Unfortunately, he can't until he knows if he will be returning to Grey's next season. Looks like we aren't the only ones left wondering after last week's season finale. TR told Access Hollywood, "If you're supposed to report back to work in a month and a half, I would really like to know that because I would like to know if I can shave my head." Hopefully he'll be getting a phone call very soon so he can concentrate on what to do with his hair next.
