Jarrett Jack, New Orleans backup point guard, was arrested early Sunday morning and charged with DUI, according to the Atlanta Journal Constitution.
Police said he was also arrested for speeding and failing to "maintain his lane."
According to Snellville Police Chief Roy Whitehead, an officer stopped the vehicle and "smelled an odor of alcoholic beverage coming from the driver."
Jack, 27, who has an Atlanta address, was stopped in a black Mercedes-Benz shortly after 4 a.m. for speeding on U.S. 78 westbound near McGee Road, Snellville police said. He was driving 66 in a 45 mph zone, police said.
Because the police department's Intoxilyzer was not working, Jack was given the test at the Gwinnett County Jail, according to Whitehead.
Whitehead said that Jack registered a .079 at 5:38 a.m., an hour and a half after the traffic stop.
"In general, alcohol dissipates from the system at approximately .02 grams per hour," Whitehead wrote in an email. "Therefore, he would have been over the limit of .08 at the time of the driving infraction."
Jack was selected with the 22nd overall pick in the 2005 draft by the Denver Nuggets. He currently averaged 7.6 points and 2.8 assists per game with the Hornets.
