The Arizona Cardinals defensive lineman was clearly agitated while posting a series of tweets during the incident Monday. Dockett tweets that police told him he was pulled over because he was speeding, and they wanted to search his car.
"I don't know why the police always messing w/me," he tweeted.
He says he refused to allow police to start a search without a warrant. Dockett eventually tweeted he was about to be let go, and updated his Twitter page a few hours later by saying he did not receive a ticket from police.
It was unclear where the incident occurred, and agent Drew Rosenhaus did not immediately respond to an email requesting comment.
Dockett, who has played seven NFL seasons, frequently uses Twitter and has more than 70,500 followers.
