Auburn true freshman quarterback Bo Nix threw a 26-yard touchdown pass to Seth Williams with 9 seconds remaining and the 16th-ranked Tigers opened the season with a 27-21 comeback win over No. 11 Oregon on Saturday night.

Nix barely converted a fourth-and-3 at midfield on the final drive when he tucked and ran. Only the nose of the ball was past the chain when officials measured. Then on third-and-10 from the Oregon 39 with no timeouts, Nix hit Williams for 13 yards and then found him again on the next play to put Auburn ahead for the first time.

The Tigers, who trailed 21-6 late in the third quarter, delivered another opening-weekend blow to the Pac-12. They beat the Pac-12’s highest-ranked team in a season opener for the second year in a row – No. 6 Washington lost to them 21-16 in Atlanta last year.

Nix finished 13-of-31 passing for 177 yards and two touchdowns and also ran seven times for 42 yards. JaTarvious Whitlow ran 24 times for 110 yards for the Tigers.

Justin Herbert, who bypassed early entry in the NFL draft to return to Oregon, was 28-of-37 passing for 242 yards with a touchdown.

Herbert was also injured for one play after being hit by an Auburn Linebacker but was able to return to the game.
