This is rarely promising news for a show:
Sons of Tucson is recasting a pair of key roles.
The sitcom, which stars Tyler Labine (pictured) as a slacker enlisted by a trio brothers to pose as their father while their real dad serves time for a white-collar crime, is seeking two new actors.
A pair of sons - Robby, 8, and Brandon, 15 - will be replaced.
They were originally played by Troy Gentile and Davis Cleveland. No word yet on why the show is seeking their replacements.
