ABC's Sunday night drama Brothers & Sisters has picked up veteran actor Stephen Collins for a gay role, TV Guide reported.

Collins will play Charlie, the love interest of Uncle Saul (played by Ron Rifkin).

The sixty-two-year-old Collins is best known for playing Protestant Reverend Eric Camden, the father of seven, for over a decade on the Aaron Spelling-produced 7th Heaven, and can be currently seen on ABC's No Ordinary Family, in which he plays Julie Benz's possibly corrupt boss.

In last year's season finale, Uncle Saul learned that he is HIV-positive. Charlie will help Saul come to terms with his diagnosis.

“Even though he didn't know his diagnosis until recently, I have a feeling Saul has been dealing with this for years,” Producer David Marshall Grant said. “He hasn't been frequenting gay bars.”

TV Guide is reporting that Collins is only scheduled to appear in next season's fourth episode.

Brothers & Sisters will also pursue the parenting storyline of gay couple Kevin Walker (Mathew Rhys) and Scotty Wandell (Luke Macfarlane), who are expecting a child via surrogate, when the drama returns to ABC on September 26.
