The arrest means a mandatory three-game suspension for Humphrey under Georgia's Athletic Association policy that requires an athlete arrested on an alcohol-related offense miss 10 percent of his or her season's games. He will miss Saturday's game against Florida and games next week against South Carolina and Tennessee.
Humphrey, 20, was booked into the Clarke County jail at 2:12 a.m. Thursday, about four hours after Georgia lost 67-59 to Vanderbilt. He was released at 3:45 a.m. on $1,000 bond.
Humphrey still is on probation from a November incident in which campus police found a knife in his room while searching the room for suspicion of marijuana possession, but that probation is specifically related to a weapon-related charge, team spokesman Tim Hix said.
Humphrey, who is averaging 13.1 points per game, missed one game following that arrest.
Georgia has already dismissed two players from this year's team and seen another quit.
