Seahawks backup quarterback Josh Portis will be arraigned May 28 for driving while intoxicated, after being arrested on May 5.

Portis was pulled over at 9:26 p.m. on May 5 after he was observed driving 80 miles an hour in a 60-mile-an-hour zone exiting the Mount Baker Tunnel on eastbound I-90 in a 2008 Range Rover.

A report from the Washington State Patrol says the officer noticed “a strong odor of intoxicants coming from the vehicle” and that the driver “had watery bloodshoot eyes.”

Portis later submitted to two blood tests and registered blood alcohol concentration readings of .092 and .078. The legal limit in the state of Washington is .080. He was charged with a gross misdemeanor.

The arraignment will be in the Redmond Courthouse.

Portis is expected to compete with Brady Quinn and Jerrod Johnson for the backup job behind Russell Wilson. Johnson had a solid showing at the rookie mini-camp two weeks ago.

Portis was re-signed by the Seahawks in April to a two-year contract with a base salary of $480,000 in 2013.
