FAYETTEVILLE, Ark. -- Buffalo Bills running back Jonathan Williams has been arrested in northwest Arkansas on a misdemeanor charge of driving while intoxicated.

Fayetteville police say an officer pulled over the former Razorback early Thursday after seeing his vehicle weave within its lane. A police report says Williams told the officer that he had one beer, but he refused to take a blood-alcohol test, citing previous advice from his agent. Williams was booked in the Washington County jail and released two hours later.

Williams was a fifth-round pick this year for the Bills after sitting out his senior season at Arkansas with a torn ligament in his foot. At Arkansas, Williams had 2,321 yards rushing and 16 touchdowns and added 345 yards receiving and six touchdowns in 36 career games.
