FX has set fall premieres for the returns of "Sons of Anarchy," "It's Always Sunny in Philadelphia" and the penultimate season of "Nip/Tuck."

Launching first for FX is "Sons of Anarchy," which moves to Tuesday nights for its 13-episode second season, starting on September 8 at 10 p.m. ET. This will give the motorcycle gang drama, featuring returning stars Charlie Hunnam, Katey Sagal and Ron Perlman, a head-start before the networks begin their fall roll-outs.

FX isn't interested in overall viewership numbers, but "Sons of Anarchy" averaged 1.2 million viewers among men 18-34 for its first season, with 1.9 million viewers among adults 18-34.

Premiering next is the fifth season of the outlandish comedy "It's Always Sunny in Philadelphia." The 12-episode season will begin on Thursday, September 17 at 10 p.m. ET. Naturally, stars Rob McElhenney, Glenn Howerton, Charlie Day, Kaitlin Olson and Danny DeVito will all be back.

"Sunny" will be facing off with NBC's "The Jay Leno Show" in an hour that NBC keeps telling viewers has been starved for comedy in recent years.

Finally, the 10-episode sixth season of "Nip/Tuck" will premiere at some point during October. The show has already wrapped production on its last season as well, but the penultimate episodes will feature guest stars Vanessa Redgrave, Rose McGowan, Mario Lopez, Barry Bostwick and Gilles Marini.
