(Eugene, OR)  --  Oregon may have just landed its replacement for NFL-bound Heisman Trophy winning quarterback Marcus Mariota.  Eastern Washington quarterback Vernon Adams Jr. announced on Twitter that he will play out his final season of eligibility with the Ducks.  Adams Jr. has been the runner-up in each of the past two seasons for the Walter Payton Award, which honors the FCS player of the year.  He is eligible to play immediately next season under the NCAA's graduate student transfer-exception rule.  Oregon opens its 2015 campaign at home on September 5th against Adams' former Eastern Washington team.
