Cook, 24, was arrested without incident after someone called 911 around 2 a.m. CT to report hearing people across the street yelling and screaming, Eden Prairie police spokeswoman Katie Beal said.
The second-year pro was booked on two charges, including one count of domestic assault, and was being held without bail Saturday at Hennepin County jail, according to online records. Prosecutors have 48 hours in which to charge Cook, who has a court hearing scheduled for Monday morning.
Vikings' spokesman Bob Hagan said Cook has been ruled out of Sunday's home game. The team had earlier issued a statement saying it didn't plan to comment about the arrest until it could learn more about what happened.
"We take this matter very seriously and are still gathering all the details of the incident," the Vikings said.
Earlier this year, Cook was accused of pulling a gun on a neighbor in his home state of Virginia. A judge found him not guilty of a misdemeanor count of brandishing a firearm, saying there was insufficient evidence to convict him.
Vikings coach Leslie Frazier had a talk with Cook during the offseason to reiterate the importance of staying out of trouble off the field, and the second-year player emerged as perhaps the most reliable cornerback during the team's 1-5 start. At 6-foot-2, he has the size to match up with taller receivers and the speed to keep up with smaller ones.
Cook has started in Winfield's place over the last three games opposite Cedric Griffin, who has yet to return to his old form while coming off his second torn anterior cruciate ligament in the last two years. Without Cook, Asher Allen will likely step into the starting role with Marcus Sherels moving into the nickel back spot. Rookie Brandon Burton also could be activated to provide depth.
Even before the incident with Cook, Frazier said his short-handed secondary would be challenged against their undefeated division rivals.
"They do a lot of four- and five-wideout sets; more so than most teams that you play," Frazier said Friday. "You would like to have all hands on deck, but the guys that are going to play are going to be ready to go and we are going to need them to step up and play big for us."
