Carmack—also known for playing Marissa's boyfriend Luke Ward in season one of The O.C.—is joining for "a major recurring role," according to The Hollywood Reporter and is set to play an orthopedic surgeon who is so talented, he is referred to as an "Ortho God."
While details surrounding his character are slim, season 15 is said to be the "season of love." As a result, there is chatter that Carmack's character and Meredith Grey (Ellen Pompeo) might strike up a romantic relationship as she is finally ready to move on following the tragic death of her beloved husband Derek Shephard (Patrick Dempsey) in season 11.
Kim Raver is also set to return to the ABC drama as a regular, once again playing Dr. Teddy Altman.
“I am thrilled to reprise the role of Dr. Teddy Altman as a regular,” Raver said in a statement. “Returning to Shondaland with the incredibly talented [showrunner] Krista Vernoff, Ellen Pompeo and the amazing cast is heavenly. I have a special place in my heart for Teddy and feel very lucky to have the opportunity to continue her story.”
The exciting new cast announcements come after fans were forced to sadly say goodbye to beloved characters Dr. April Kepner (Sarah Drew) and Dr. Arizona Robbins (Jessica Capshaw).
