Baltimore Ravens running back Byron “Bam” Morris is expected to turn himself in in response to an arrest warrant issued as part of an attempt to revoke his 10-year probation on a drug conviction.

Morris’ attorney, Jay Ethington, said his client might also turn himself in early next week but is taking the matter very seriously. Ethington said Morris could surrender as early as Friday or as late as next week.

District Attorney Ray Sumrow of Rockwall, Texas, 25 miles east of Dallas, sought the arrest warrant. He said Morris’ probation should be revoked because he violated two conditions of his probation by using alcohol and by failing to report to his probation officer seven times from July 1996 to August 1997.

Sumrow said he has not decided what punishment to recommend and wants to meet with the probation officials who supervise Morris to determine the best course.

Morris pleaded guilty to marijuana possession after his arrest in March 1996 on Interstate 30 near Rockwall. An officer found more than 5 pounds of marijuana in the trunk of Morris’ car.
