Akeem Spence is facing a one-game suspension for a January 2014 marijuana arrest, first reported by Ian Rapoport of NFL Network. The Tampa Bay Buccaneers defensive tackle saw his charges dismissed after a pre-trial diversion program, but will still have to miss one game after he returns from injury under the league's substance abuse policy. Generally speaking, first offenses against the substance abuse policy cause players to be placed on a testing program, not facing a suspension, so this probably wasn't be Spence's first substance abuse incident.
That's not Spence's biggest concern, though: he's set to miss "several months" with a back injury and may actually have to fear for his spot on the team.
