MIAMI BEACH, Fla. — Former NBA player Antoine Walker has been charged with suspicion of drunken driving in Miami Beach.

Police say Walker was driving a black Mercedes without the lights on when he was pulled over early Monday morning. Police say officers smelled alcohol and that Walker looked sleepy.

Police say he refused to take a Breathalyzer test.

Walker was a three-time All-Star forward for the Boston Celtics and helped the Miami Heat win the NBA championship in 2006.

Walker struggled in 46 games with the Minnesota Timberwolves last season. His contract was bought out by the Memphis Grizzlies in December but he hasn't played this season.

Walker was being held on a $1,000 bond and did not immediately have an attorney.
