Matthew Morrison says he's returning to 'Grey's Anatomy' for 'big' season 14 arc

Looks like there's drama brewing between Alex and Jo's estranged husband.

Matthew Morrison appears to be headed back to Grey's Anatomy in the upcoming 14th season. The Glee alum all but confirmed his return as Dr. Paul Stadler -- and it sounds like it'll be quite a meaty arc.

Speaking with The Argonaut, Morrison let it slip that he was returning in a major way on ABC's hit medical soap.

"I have a big role in Grey's Anatomy coming up," the 38-year-old actor and father-to-be told the outlet. ABC declined to comment.

Morrison made his debut on Grey's in the penultimate episode of season 13, where Alex (Justin Chambers) spent much of his time following Paul's every move at a Seattle medical conference. Though Alex had visions of beating up Jo's abusive hubby, their only interaction was a brief moment outside when Alex passed on sharing a cab with Paul, who gave him a curious look.

Earlier on Friday, ET confirmed that Grey's was replacing Bridget Reganas Megan Hunt, Owen's presumed dead sister, with Timeless star Abigail Spencer, due to Regan's commitments on The Last Ship.

Grey's Anatomy premieres season 14 with a two-hour episode on Thursday, Sept. 28 at 8 p.m. ET/PT on ABC.
