Jackson to serve 4 days in jail

San Diego Chargers receiver Vincent Jackson pleaded guilty to a 2009 DUI charge on Monday and received a four-day jail sentence and five years probation.

It is unclear when Jackson will serve his jail time.

Since joining the Chargers, Jackson has been arrested twice for suspicion of driving under the influence. He pleaded guilty in a 2006 case and was on probation when he was arrested again last January.

City Attorney's Office spokeswoman Gina Coburn said Jackson was given the standard sentence for a DUI with one prior, including a $2,408 fine and 10 days of public work service. He also was given an additional five days of public work service on the 2006 DUI.

The jail time can be served as work release, Coburn said, and Jackson, who entered his plea on Monday, can report between now and March 23.

With the guilty plea, Jackson likely will be subject to the NFL's personal conduct policy and could face at least a one-game suspension in the 2010 season.

Jackson faces arraignment on March 2 for driving with a suspended license. He was handcuffed briefly and had his car impounded following a traffic stop just a few hours before the Chargers' playoff loss to the New York Jets. Jackson was pulled over for playing loud music. He was cited for driving with a suspended license and expired tags.

Jackson likely will be a restricted free agent this offseason, unless the NFL and its players can agree to a new contract before March 5. If a new contract is agreed to, then Jackson would be an unrestricted free agent.

Jackson enjoyed his best NFL season in 2009 with 68 catches for 1,167 yards and nine touchdowns.

Chargers general manager A.J. Smith didn't return a call to The Associated Press seeking comment Tuesday.
