Celtics' forward Paul Pierce was handcuffed by Las Vegas police early Sunday after he was uncooperative during a traffic stop for driving erratically, according to The Las Vegas Review-Journal.

Pierce reportedly "calmed down" after fifteen minutes and the handcuffs were removed soon after.

"We find this happens a lot of times," public information officer Bill Cassell said. "Someone is a little agitated, and when they?re placed in handcuffs they rethink things."

A breathalyzer test showed that Pierce registered below the .08 level that defines legal intoxication in Nevada.

"We don?t cite everybody we stop," Cassell added. "Sometimes we give just a verbal warning. It?s based on the totality of the circumstances."
