Grey's Anatomy News: Four Cast Member Signed on For Two More Seasons of the ABC Medical Drama.

Four more cast members have signed on for two more years of the ABC Medical Drama, Grey's Anatomy. While Sandra Oh's character, Christina Yang will be leaving Seattle Grace Hospital after this season; it looks like none of our other favorite cast members will be joining her.

Entertainment Weekly confirms that four of our favorite Grey's Anatomy stars will be around for at least two more seasons. Justin Chambers, Sara Ramirez, James Pickens Jr., and Chandra Wilson have all inked new deals to stay on until season 12 of the show.

Their characters of Alex Karev, Callie Torres, Richard Webber, and Miranda Bailey will be joining Meredith Grey (Ellen Pompeo), and Derek Shepherd (Patrick Dempsey) for at least the next two years, should the series be picked up for these additional seasons by the network.

An official renewal for the series is likely to come in the next few weeks, when all the major networks reveal their fall TV schedules.

Chambers, Pickens Jr., Wilson, Pompeo, and Demsey, are the only remaining five cast members that have been with the show since it premiered back in 2005.

The Grey's Anatomy season finale, which will be Oh's last episode of the series, will air May 15 on ABC.
