STANFORD, Calif. (AP) - Stanford coach David Shaw is moving closer to a change at quarterback.

With Josh Nunes struggling to consistently move the offense, Shaw said Tuesday that backup Kevin Hogan will take more snaps at Colorado on Saturday.

The plan is for Hogan to play about 12 to 20 downs. The redshirt freshman saw only about a half-dozen snaps in each of the last two games.

Nunes has started every game since Andrew Luck left. He completed 7 of 15 passes for 136 yards and a touchdown as Stanford squeezed past lowly Washington State 24-17 last week.

Now the No. 15 Cardinal (6-2, 4-1 Pac-12) head to Boulder to face the beleaguered Buffaloes (1-7, 1-4), and future playing time could be at stake with matchups against No. 13 Oregon State and second-ranked Oregon up next.
