Dewberry admitted to Richt that he was responsible for causing damage to property at St. Mary's Hospital on Saturday morning after two Georgia players were hospitalized after they were hit with bottles in a brawl at a downtown club, the coach said.
The fight occurred the night after the Bulldogs were ranked No. 1 in the USA Today Coaches' Poll going into the 2008 season, which begins Aug. 30.
Security guards at the hospital told police a man damaged a parking-control arm at the garage entrance. Four large potted shrubs also were turned over.
Dewberry will repay the cost of the damage, Richt said. He'll also have 20 hours of community service and early-morning running.
Dewberry is the sixth Georgia player to be suspended or dismissed from the team this off-season. Snapper Jeff Henson and defensive back Donavon Baldwin were suspended indefinitely after incidents this weekend.
"The reputation of this team has been damaged, no question," Richt said. "I don't think it's beyond repair and I don't think the reputation is ruined, but it's certainly taken some hits."
Baldwin and teammate Marcus Dowtin were hit in the head with bottles in the early-morning dust-up, Athens-Clarke County police said.
At least two other Georgia players accompanied their injured teammates to the hospital -- along with former Bulldog Michael Lemon, who later was arrested outside the hospital for underage possession of alcohol.
No arrests have been made in connection with the brawl.
Baldwin is a junior free safety who had already gotten a one-game suspension for a DUI arrest in January.
Lemon, a former defensive end, was kicked off the team last month for an aggravated battery charge stemming from a fight in June.
