EUGENE, Ore. (AP) Vernon Adams threw for two touchdowns but left his much-anticipated debut after a scary fourth-quarter hit, and No. 7 Oregon defeated his former team, Eastern Washington, 61-42 to open the season on Saturday night.

Royce Freeman ran for a career-high 180 yards and three scores for the Ducks, who didn't appear to have slipped much offensively without Heisman Trophy winner Marcus Mariota.

Adams, who transferred to the Ducks for his final year of eligibility, was ushered to the locker room after he staggered getting up from a late hit by Eastern Washington's John Kreifels, who was ejected.

Adams, a repeat Big Sky Conference offensive player of the year, was replaced by Mariota's backup last season, Jeff Lockie. Adams' condition was not immediately known.

Jordan West, who took over as Eastern Washington's quarterback after Adams' departure, threw for 293 yards and three touchdowns.
