TYLER, Texas (AP) _ Cincinnati Bengals defensive back Tremain Mack is back in jail, finishing a 20-day sentence from a drunken driving conviction more than two years ago.

Mack entered the Smith County Center Jail on Wednesday to complete his sentence. Mack originally was scheduled to serve the time following the 1999 season, but the kick returner broke his wrist in the Pro Bowl and was allowed to put off the jail time.

Mack was released from jail in Cincinnati on Feb. 7 after serving nearly a month for violating his probation on other drunken driving convictions.

The NFL is considering whether to fine or suspend Mack, 26, who has a history of alcohol-related problems. He was convicted of drunken driving in 1997 and 1998, resulting in jail sentences and an eight-game suspension for violating the league's substance abuse policy.

His driver's license also was suspended and he was prohibited from driving. A Cincinnati television station filmed him driving in November, a violation that resulted in the one-month jail stay.
