Quarterback Vernon Adams put on Oregon roster after completing class

The Oregon Ducks have already passed their most important test of training camp.

It was a math test.

Ducks fans in Eugene and across the country held their breath Thursday as they waited for results of a test that quarterback Vernon Adams had to pass to become eligible.

Adams, a fifth-year graduate transfer from Eastern Washington, is expected to eventually supplant Marcus Mariota as the team’s starting quarterback.

Adams needed to pass the math test to complete his degree at Eastern Washington and join Oregon this season.

“Thank God,” Adams posted on his social media site Thursday evening. It included a hash tag #timetogettowork

He is expected to join the Ducks for Friday practice. Adams and junior Jeff Lockie will be competing for the job to replace Mariota, who won last year’s Heisman Trophy in leading Oregon to the national title game.

Adams is moving up a division from 1-AA, but has already ripped apart two Pac-12 teams in non-conference games.

In 2013, he led an upset at Oregon State in which he threw for 411 yards and four touchdowns and rushed for 107 yards and two touchdowns. Last year, he threw for seven touchdowns and 475 yards in a near upset at Washington.

Adams, at the very least, gives Oregon depth at a position that falls off sharply after Lockie.

At best, Adams could be the key to another playoff run. The Ducks are otherwise loaded with offensive talent.

Adams was a former prep star at Bishop Alemany in Southern California.

Just to tie a bow around this story, Oregon opens the season Sept. 5 against Eastern Washington, Adams’ former school.
