The tv schedule for Saturday, Sept. 20 is out, and Oregon St.'s next game, when the Beavers host San Diego St., will be another night game, with a 7:30 PM start. Fox Sports 1 will have the coverage.
It is 1 of 3 of the day's 6 Pac-12 games that will be night games, with the Oregon at Washington St. game also at 7:30 PM PDT (on ESPN), and the California at Arizona game (which obviously has to be a night game) at 7 PM AST & PDT (on the Pac-12 channel).
At least Oregon St. avoided relegation to the Pac-12 channel, and achieved national distribution.
There is also a morning game, with Hawaii visiting Colorado at 11 AM PDT (at least it will be noon MDT) on the Pac-12 channel.
Utah gets national coverage for their game at Michigan at 12:30 PDT (3:30 EDT), with split coverage regionally between ABC & ESPN2, and the ONLY game of the 6 in the prime mid/late afternoon time slot is Georgia St. at Washington, which starts too early, at 3 PM PDT (vs. 3:30 or 4, which would avoid audience losing overlap with the 12:30 PM starts), but the game is "banished" to the Pac-12 channel.
