Report: Darren Carrington suspended

— -- DALLAS --  Oregon Ducks receiver Darren Carrington did not make the trip to Dallas for Monday night's College Football Playoff Championship Presented by AT&T against Ohio State, the school confirmed Friday. 

Comcast Sportsnet Northwest reported that Carrington, a freshman from San Diego, failed an NCAA-administered drug test, testing positive for marijuana.

Oregon spokesman Dave Williford confirmed Carrington did not make the trip, but the team wouldn't address the situation until coach Mark Helfrich appears at Saturday morning's media day.

The Ducks arrived in Dallas on Friday night.

If Carrington doesn't play against the Buckeyes on Monday night, it would be a big blow for Oregon's high-powered offense.

Carrington had more than 100 receiving yards in each of the Ducks' past two games. He had seven catches for 126 yards with one touchdown in a 51-13 victory over then-No. 8 Arizona in the Pac-12 championship game Dec. 5, and then had seven catches for 165 yards with two touchdowns in a 59-20 win over No. 3 Florida State in the Rose Bowl Game Presented by Northwestern Mutual on New Year's Day.

The Ducks are already expected to be without freshman receiver Devon Allen, who injured his knee on the opening kickoff of the Rose Bowl. Allen is Oregon's No. 2 receiver with 41 catches for 684 yards and seven touchdowns. Tight end Pharaoh Brown has also been sidelined for several games with a leg injury.

The Ducks still have three players who have caught more than 20 passes this season: converted running back Byron Marshall, sophomore Dwayne Stanford and freshman Charles Nelson.
