FOX has opted to not renew TERMINATOR: THE SARAH CONNOR CHRONICLES, reports ENTERTAINMENT WEEKLY'S Michael Ausiello.

"It's done," maintains a source close to the show. "Everyone has pretty much known for a couple of weeks." Adds a network insider: "Consider it canceled."

FOX's rep told Ausiello that no decision has been made yet officially, and the network is waiting until May 18 when the fall schedule is announced.
