Cook told the Star Tribune that he was riding his bike near his Lynchburg, Va., home Saturday when a neighbor began yelling at him. He said the neighbor wrongly believed Cook had called police about the neighbor's brother.
"You're not going to scream at me like I'm your child so I screamed back at him," Cook told the newspaper. "He thought that I called the police on his brother for some reason. Why would I do that?"
Cook said he had recently received a license to carry a concealed weapon, but denied pulling a gun on the man as WSET-TV reported. Lynchburg Police Capt. Ryan Zuidema told The Associated Press that Cook is accused of brandishing a firearm.
"It's just crazy," Cook told the newspaper. "I just have to deal with it the best way I can. I wish it didn't happen. I wish I would have never got in an argument, but that's what happened."
The Vikings are not allowed to have contact with Cook because of the NFL lockout.
