NBC has pushed back the second season premiere of "Southland" by nearly a month.

The John Wells produced cop drama, which launched on Thursday nights last spring, will now air its first new Friday episode on October 23, rather than the previously announced Sept. 25.

This moves "Southland" out of the way of the launches of CBS' transplanted "Medium" and FOX's second season drama "Dollhouse."

The official NBC party line, accepted by both of the trade paper reports on the rescheduling, is that NBC wants the extra weeks to give "Southland" the proper marketing support. In the interim, "Dateline" will air in the 9 p.m. Friday slot leading -- as all NBC 9 p.m. shows now do -- into "The Jay Leno Show."

"Southland" premiered following the series finale of "E.R." and pulled in 9.7 million viewers. The show was down to under 6.5 million viewers by its first-season finale.
