PASADENA, Calif. -- Oregon redshirt freshman wide receiver Devon Allen left the Ducks' 59-20 rout of Florida State in Thursday's Rose Bowl Game Presented by Northwestern Mutual with an apparent knee injury after fielding the opening kickoff.

He is expected to miss the College Football Playoff National Championship Presented by AT&T on Jan. 12, a source told Fox Sports after the game.

Allen left the sideline in a wheelchair with his right knee heavily bandaged shortly after suffering the injury.

Allen has accounted for 684 yards and seven touchdowns on 41 receptions this season.

He's also a member of the Oregon track team. He won the 2014 NCAA national title for the 110-meter hurdles and won the 110-meter hurdles at the 2014 USATF Outdoor Championships in June.

Allen's apparent knee injury only adds to the list of those the Ducks have suffered this season. Most notably, Oregon recently lost cornerback Ifo Ekpre-Olomu to a season-ending knee injury before the College Football Playoff.
