Taye Diggs joins Grey's Anatomy spin-off

Taye Diggs will star opposite Kate Walsh in ABC's potential spin-off from hit medical drama Grey's Anatomy.

The show will test the waters as a backdoor pilot, an expanded two-hour episode of Grey's slated to air in May. It will center on neonatal surgeon Addison Shepherd (Walsh), a character who has enjoyed a strong following from fans since she was introduced at the end of the hot surgical drama's first season.

It is understood that the backdoor pilot episode will feature Shepherd on the verge of leaving Seattle Grace, a scenario that will be triggered if ABC goes with the spin-off for next season. There were no details on the character Diggs will play.

Grey's creator/executive producer Shonda Rhimes is writing the episode and is expected to shepherd the potential series. Meanwhile, Rhimes' other ABC pilot, about female journalists, has been pushed to a summer production start.

Diggs' casting in the Grey spin-off stems from a new talent-holding deal he recently signed with ABC TV Studio, where Grey's Anatomy is based. He starred in two drama series for the studio, Kevin Hill for UPN and Day Break for ABC.
