Snellville Police Chief Roy Whitehead said in an e-mail Monday the 27-year-old former Georgia Tech star was pulled over early Sunday by an officer who clocked him at 66 mph in a 45-mph zone. Police say Jack's Mercedes was also weaving.
Whitehead says Jack failed a field sobriety test, then was taken to the Gwinnett County jail and given a breath test, which measured just under the legal limit of .08 more than an hour after Jack was stopped.
Jack was also charged with failure to maintain a lane. He was released Sunday night.
He did not immediately return a call for a telephone number listed for him in Atlanta.
