Oregon State quarterback Sean Mannion is returning for his senior season.
Mannion, who has already graduated with a bachelor's degree in liberal studies, announced his decision Monday in a statement released by the Beavers.
Mannion set the Pac-12's single-season record for passing yards with 4,662 this past season. He threw an Oregon State-record 37 touchdown passes, third-most for a single season in conference history.
Before making his decision, he consulted the NFL Draft Advisory Board and was projected as a third-round selection.
Mannion was widely considered a Heisman hopeful after the Beavers opened 6-1, but Oregon State dropped its last five regular-season games.
The Beavers capped the season with a 38-23 victory over Boise State in the Hawaii Bowl to finish 7-6.
