BRIEFLY : JAIL TERM OVER FOR BAM MORRIS.

Byline: Daily News Staff and Wire Services

Free agent running back Bam Morris was released Saturday from the Rockwall County jail in Dallas after serving 89 days of a 120-day sentence for marijuana possession.

Morris, 26, is an unrestricted free agent after the Baltimore Ravens cut him Jan. 28. If he commits the crime again, he could face 10 years in prison.

He was placed on six years' probation, fined $7,000 and ordered to perform 200 hours of community service. But he ended up having to serve jail time after admitting he missed seven meetings with his probation officer from July 1996 to August 1997.

He helped lead Pittsburgh to the Super Bowl in 1996 and was the game's leading rusher, but he was released months later after his legal troubles began. He played for the Ravens the past two seasons, although the NFL suspended him from the first four games of the 1997 season for violating the league's substance abuse policy.
