I guess CJ's speed ain't exactly legal in Minnesota.
Edina police spokeswoman Molly Anderson says Peterson was pulled over just before 8:30 p.m. Saturday.
Peterson was driving his BMW on a state highway in a 55-mph zone. Anderson says he was given a citation and allowed to drive away. She called it a "very routine" traffic stop.
Peterson tells The Associated Press he didn't realize how fast he was going. He said he "got a little speeding ticket" and said he planned to be more careful.
The stop happened the night before Peterson ran for 85 yards and a touchdown in a 36-10 victory over Chicago. He also fumbled twice.
