Oregon was forced to bench two players because of failed drug tests days before the team competes in the first College Football Playoff title game.
Wide receiver Darren Carrington and running back Ayele Forde did not travel with Oregon for Monday's national championship game against Ohio State after each failed NCAA-mandated drug test. Carrington tested positive for marijuana; the results of Forde's test weren't disclosed.
Oregon coach Mark Helfrich insisted Saturday that the team remained focused.
"Unfortunately, we've been tested in the realm of guys not being available for whatever reason all season long," Helfrich said. "And our guys have stepped up."
The loss of Carrington is particularly difficult for the Ducks, who already are short at receiver.
The players were tested before the team's Rose Bowl appearance, a person with direct knowledge of the tests told the Associated Press.
Not having Carrington leaves the Ducks down two key receivers against Ohio State. Carrington, a 6-2, 191-pound redshirt freshman, had seven catches for 166 yards and two touchdowns in Oregon's Rose Bowl victory over Florida State.
Last week, Oregon lost redshirt freshman receiver Devon Allen on the opening kickoff because of a knee injury.
