The Hawks have agreed to a one-year, veteran-minimum contract with Jarrett Jack.
Jack, who played at Georgia Tech, most recently was with the Nets before a torn ACL ended his campaign in January of last season.
Jack, 32, averaged 12.8 points, 7.4 assists, 4.3 rebounds, 1.1 steals and 32.1 minutes in 32 games last season before he was injured.
