WHAT'S AT STAKE

The Ducks are already headed to the Pac-12 Championship game, although their opponent has not been determined. At No. 2 in the College Football Playoff rankings, it appears fairly certain that if the Ducks can get past the Beavers and win the league championship game, they're in the first playoffs. Oregon State needs one more win to become bowl eligible. If they lose, it will mark the end of Sean Mannion's stellar career with the Beavers.

KEY MATCHUP
