Former Jacksonville Jaguars standout Jimmy Smith currently is serving a six-year sentence in Mississippi prison on two charges, the Mississippi Department of Corrections confirmed Monday.

Smith is serving four years for cocaine possession and two more years for possession of a firearm by a convicted felon. Smith had substance-abuse problems throughout his NFL career. He was suspended four games in 2003.

It's a sad story, although not a shocking one for one of the top two or three greatest players in Jaguars history. Smith, a five-time Pro Bowl selection, already had at least one arrest related to substance abuse since his NFL career ended in 2006. His retirement came as a surprise because he gained 1,023 yards in his final season.
