Quinton Knight transferred to Cal State Fullerton from Sam Houston State and played one season for the Titans. He signed as a free agent with the CFL's Toronto Argonauts in 1987 although he never suited up for a regular season game for the club.
In 1988, Knight began a much-travelled career in the Arena Football League by signing with the New York Knights. There was speculation that Knight would be a territorial pick by the Los Angeles Cobras but they left him unprotected and he was the first lineman drafted by the New York club. Knight finished the year second in the league with 9 quarterback sacks. The New York Knights folded and the AFL played just a 4-game season in 1989 with Knight playing on a resurrected Denver Dynamite team for two seasons. Knight compiled 7.5 sacks in his two years with the Dynamite and was named to his third consecutive 1st Team All-AFL Team in 1990. In 1991, Knight played for the Orlando Predators.
In 1992, Knight wore this jersey for the Detroit Drive, helping the team to their fourth and final Arena Bowl title. The Drive (and many teams in Arena at the time) wore Bike jerseys. Another trademark of early AFL jerseys is the lack of use of nameplates and screened player names directly on the back of jerseys. Knight did not play in 1993 but returned in 1994 to play for the Massachusetts Marauders, the former Detroit Drive. Knight would finish his career with the Miami Hooters in 1995. Knight totalled 21 quarterback sacks in his AFL career.
