ATHENS, Ga. -- Georgia running back Isaiah Crowell, who was in and out of Bulldogs coach Mark Richt's doghouse as a freshman, was dismissed from the team Friday after being arrested on weapons charges by Athens-Clarke County Police overnight.
Crowell, from Columbus, Ga., was arrested and charged with two felonies and a misdemeanor, according to the Athens-Clarke County Jail booking report.
Crowell, 19, was charged with a felony count of possessing a weapon in a school zone, a felony count of altered identification mark and a misdemeanor count of possession/carrying a concealed weapon.
He was arrested around 2:20 a.m. ET after being stopped at a vehicle checkpoint near the Georgia campus and booked at 3:37 a.m.
Crowell was dismissed from the team in the late afternoon.
"We have a dedicated and committed group of men who are working hard to prepare for the coming season," Richt said in a news release. "Our total focus will be directed toward the team and this effort."
Crowell was released from Athens-Clarke County Jail at 12:44 p.m. on $9,500 bond.
According to a police report issued Friday, the serial number on a 9-millimeter Luger found under the driver's seat had been scratched off completely, but Crowell denied knowing a gun was there, saying other people drive his car.
Police said the altered ID-mark charge stems from the tampered serial number.
Crowell could face a fine of up to $10,000 and a jail sentence between two and 10 years if found guilty of weapons possession on school property, while a guilty verdict for criminal use of an article with an altered ID mark carries a sentence between one and five years.
Crowell also said teammates Blake Tibbs, Quintavius Harrow, Josh Harvey-Clemons and Sheldon Dawson, who were passengers in the car, had just left a club called Aftermath, according to the police report.
The arresting Athens-Clarke County Police officer stated she smelled marijuana inside the 2005 Mercury Grand Marquis that Crowell was driving.
"[Crowell] consented to a search of the vehicle, and officers didn't find the marijuana," Athens-Clarke County Police spokeswoman Hilda Sorrow told ESPN.com on Friday morning. "There were other occupants inside the car and they consented to a search, but the marijuana wasn't found. During the search of the vehicle, officers found a gun under the driver's seat. After discovering that the ID number had been altered [on the gun], Mr. Crowell was arrested and charged. Marijuana was never found inside the car."
Crowell, ranked as the country's No. 1 running back and No. 4 prospect by ESPN Recruiting in 2011, had a rocky first season with the Bulldogs.
He ran 185 times for 850 yards with five touchdowns as a freshman but was dogged by disciplinary problems throughout the previous summer.
Crowell was benched for the first quarter of the Bulldogs'
33-28 victory over Vanderbilt on Oct. 15 for disciplinary reasons and then was suspended for UGA's 63-16 victory over New Mexico State.
Crowell was hampered by an ankle injury late in the season and ran only 15 times for 31 yards in the Bulldogs' last four games.
He was booed by UGA fans after limping off the field with an ankle injury in the first half of the Bulldogs' 42-10 loss to LSU in the SEC championship game at the Georgia Dome on Dec. 3.
Marshall, who enrolled at UGA in January after graduating from Millbrook High School in Raleigh, N.C., offered support for his Bulldogs teammate on Twitter on Friday morning: "Pray for Isaiah & that he will learn from his mistake."
