An incident report released by the California Highway Patrol on Tuesday described Lynch driving a Ford Econoline van and having two near collisions with two other vehicles driving in adjacent lanes.
Authorities say Lynch was pulled over around 3:20 a.m. PT Saturday in Emeryville and showed signs of intoxication. After multiple field sobriety tests, Lynch was arrested and booked into jail, where he was cited and later released. Lynch took a chemical test.
Teresa Drenick, director of communications for the Alameda County district attorney's office, said Lynch was scheduled for an Aug. 14 preliminary court appearance and that any decision on charging Lynch will be made by then.
Drenick said the office has yet to receive the police report from the CHP.
The Seahawks said in a statement late Monday that the team is "aware of the situation with Marshawn and still gathering information."
Lynch's agent didn't immediately respond to calls from The Associated Press seeking comment.
Lynch signed a four-year contract in March that will keep him in a Seattle uniform for the prime of his NFL career. The contract is worth $31 million, including a guaranteed $18 million. Lynch rushed for 1,204 yards and 12 touchdowns last season.
Lynch came to Seattle during the 2010 season in a trade with Buffalo and after his career with the Bills stalled. Lynch ran into problems off the field in Buffalo, but stayed clear of trouble with the Seahawks until now.
He pleaded guilty in March 2009 to a misdemeanor gun charge in Los Angeles. He was sentenced to 80 hours of community service and three years' probation, and was suspended three games by the league for violating the NFL personal conduct policy.
That was Lynch's second run-in with the law following a hit-and run-accident in Buffalo in May 2008. In the earlier incident, he pleaded guilty to a traffic violation and admitted to driving away after striking a woman with his car near Buffalo's downtown bar district.
