EUGENE, Oregon — Jonathan Stewart and Jeremiah Johnson combined for 249 yards on the ground as the Oregon Ducks opened the season with a 48-10 victory over the Stanford Cardinal.

Stanford (0-1, 0-1 Pac-10) appeared to recover a Duck fumble on the first play from scrimmage, but the turnover was reversed upon video review. From that point on, Oregon’s up-tempo attack struck early and often. Quarterback Dennis Dixon completed 21 of 30 passes for 236 yards and a touchdown as the Ducks rolled up 534 yards in total offense and 298 yards on the ground.

Stanford was paced by Trent Edwards’ 224 yards on 20-for-24 passing, but rushed for only 100 yards and converted 3 of 14 third downs. One bright spot was Stanford’s lack of penalties — the Cardinal were flagged only five times to Oregon’s nine. Stanford led the conference in fewest penalty yards last season.

Stanford’s only visit to the end zone came in the second quarter. Facing 1st and 10 from the Oregon 26, Mark Bradford broke free behind the secondary. Edwards laid the ball in his hands for the touchdown, completing an 82-yard drive. Bradford later called the game a “humbling experience” against what is likely to be one of the top teams in the conference. Last year’s Duck squad went 10-2, losing only to USC and to Oklahoma in the Holiday Bowl.

Stanford also struggled with problems in the kicking game, a reliable plus for last year’s team. New placekicker Aaron Zagory was 1-for-3 on field goals, with his last attempt being blocked and returned for the Ducks’ final touchdown.

The game was notable for the contributions of several Cardinal true freshmen. Receivers Richard Sherman and Austin Yancy made their first appearances, and Toby Gerhart’s 55 yards on 16 carries showed the skill that made him California’s all-time leading rusher in high school. On defense, Sione Fua, Levirt Griffin and Brian Bulcke appeared late in the game. At least some of those players will have to become key contributors as Stanford hopes to get to its first bowl game since the 2001 season.
