Joe Hamilton's career on the Georgia Tech football staff ended less than two weeks after it started when he resigned Wednesday, a day after his arrest on charges of drunk driving, hit-and-run, marijuana possession and open container.

Hamilton, the 1999 Heisman Trophy runner-up, had hoped to use his assistant player personnel job as a steppingstone to a position as an on-the-field coach. Instead, he faces charges from an early Tuesday traffic stop on the Tech campus.

Hamilton did not immediately return a voice and a text message sent to his cell phone.

"Today, I sadly accepted Joe's resignation," Georgia Tech football coach Paul Johnson said in a released statement on Wednesday. "I know he has great love and concern for this program and always will. Both athletic director Dan Radakovich and I made it clear to Joe that we would offer any support he requires in the coming weeks and into the future. Joe will always be a part of the Yellow Jacket family."

He had joined the Tech staff April 28. His duties included assisting with recruiting and helping the players.

Hamilton apologized to Tech and professed his innocence after a bond hearing in a courtroom in the Fulton County Jail on Tuesday evening. He was released Wednesday from the jail on a $3,500 signature bond, a sheriff's spokesman said.

Hamilton was pulled over shortly after midnight by a Georgia Tech police officer because his black Ford Expedition matched the description of a car in a nearby hit-and-run crash.

Officers reported that they smelled alcohol on Hamilton's breath and asked him if he had been drinking and involved in an accident. Hamilton admitted that he had a few beers and that he hit another vehicle from behind, the report said. Hamilton failed a series of field sobriety tests.

Hamilton, 31, received his history, technology and society degree from Tech in August. Since graduating, he has been a personality on Tech's pregame radio show. He also provided color commentary on the game replays on CSS-TV.

The 5-foot, 10-inch quarterback, who played for Tech from 1996-99, led Tech to a share of the 1998 ACC championship and won the hearts of Yellow Jackets fans, who admired him all the more when he returned to school and earned his bachelor's degree last August. They were excited about the prospect of him helping the football team's on-campus recruiting efforts, and they forecast a coaching future for him as bright as his playing past.

That history made this week's news hard to take.

"To me, personally, it's a devastating blow," said Dorsey Watson, a Tech season-ticket holder since 1962. "He was an icon at Georgia Tech. He ranks right up there from an athletic standpoint with some of the great ones. It's just a real setback."
