Kristin Dos Santos at E! is reporting that Jason Ritter may join the cast of Brothers & Sisters, playing a new brother to shake up the Walker clan.

Sources are saying that Jason Ritter (last seen in The Class, Joan of Arcadia on TV) is meeting with the casting powers-that-be over at Brothers & Sisters. So, nothing is a done deal yet, but it would be great to see him join the cast.

The new brother that Jason Ritter may be playing is Ryan Walker – you may recall we learned about this secret child of William Walker’s (Tom Skerritt) in last season’s finale.

Check out the Brothers & Sisters premiere this Sunday, September 28 at 10 p.m.
