Stanley Wilson Sr., Cincinnati Bengals

Where: Super Bowl XXIII, Miami (1989)
Incident: After being late to the last team meeting before the game, the fullback was found in his hotel room sweating and shivering, high off cocaine.
Result: Wilson was left off the active roster for the game, which the Bengals lost 20-16 to the San Francisco 49ers. Already a two-time offender of the NFL's drug policy, his third violation led to a lifetime ban. That definitely blows.
