No reason was given for the absence of Seahawks All-Pro running back Marshawn Lynch from voluntary workouts, but coach Pete Carroll says Lynch is healthy.

RENTON — When the Seahawks began their offseason workouts Monday, every healthy player was present and accounted for except one — running back Marshawn Lynch.

It was unclear why Lynch was absent other than that the Organized Team Activities are officially voluntary, as Seattle coach Pete Carroll noted afterward.

“This is voluntary,” he said. “That’s the rules and the guidelines.”

Carroll said Lynch was not injured and that he had been in Seattle recently.

“He came in 10 days ago and he’s in very good shape,” Carroll said. “He’s working an intense program in his area and he is benefiting from it. We’d love to see everybody here.”

Carroll said he thought there was a chance Lynch would participate by the final OTA session on June 6.

Without Lynch, who has participated in past OTA sessions with the Seahawks, Robert Turbin worked as the first-team tailback.

Also not present was defensive end Chris Clemons, who is rehabilitating a knee injury suffered in the NFC playoff victory over Washington.

Portis charged

with DUI

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. after he was observed driving 80 mph in a 60-mph zone exiting the Mount Baker Tunnel on eastbound Interstate 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, bloodshot eyes.”

Portis initially refused to take a field sobriety test, but later submitted to two breath tests and registered blood alcohol concentration readings of .092 and .078. The legal limit in Washington is .080. He was charged with a gross misdemeanor.

Portis is expected to compete with Brady Quinn and Jerrod Johnson for the backup job behind Russell Wilson. Portis was re-signed by the Seahawks in April to a two-year contract with a base salary of $480,000 in 2013.

He spent the 2011 season on the team’s roster, and spent 12 weeks last year on the practice squad before being released in November. He has yet to play in a regular-season game.

NOTES

• Tight end Anthony McCoy suffered an ankle injury of undetermined severity late in the practice.

• Also out or limited were rookie RB Christine Michael (hamstring) and CB Tharold Simon (foot).
