[1] King's first drug violation came in 1995 during his rookie training camp after testing positive for marijuana.

Prior to the 1999 season, King signed a three-year, $6 million contract with the Indianapolis Colts and started 8 of the team's first 9 games, but was suspended again (along with teammate Tito Wooten), this time for four games due to showing up late to a meeting.

The Colts later cut King and he was suspended yet again by the league for 12 months for another drug violation and missed the entire 2000 season.

Though he was reinstated in January 2001, King chose to retire from the NFL citing the league's drug policy as a reason.

King retired from the NFL in January 2001 shortly after the league reinstated him due to his problems with the drug policy.
