There's another new doctor coming to Grey Sloan Memorial this fall and, boy, does he look familiar.

Nashville star Chris Carmack is joining Season 15 of Grey's Anatomy for a "major recurring role," according to The Hollywood Reporter. Character details are slim at the moment but we know that Carmack will be playing an orthopedic surgeon so good that he's referred to as an "Ortho God." While Grey Sloan Memorial has more cardio surgeons than one can count, the hospital has been lacking in the ortho department ever since Callie Torres (Sara Ramirez) left at the end of Season 12.

Carmack came to popular attention in 2003 when he delivered the infamous "Welcome to the O.C. b---h" line in The O.C. pilot. Since then he's played Will Lexington on the ABC/CMT soap Nashville for the past five years, so he knows his way around melodrama.

The big question around Carmack's character is: will he have anything to do with Meredith (Ellen Pompeo)? She said in the finale that she's still open for love and it doesn't look like Nick Marsh (Scott Speedman) will be returning to Seattle this season. Could Carmack be playing the next McDreamy that was televised in Season 14?

Grey's Anatomy returns with a 2-hour premiere on Sept. 27 at 8/7c on ABC.
