Humphries was selected by the
Chicago Bears in the third round (71st overall pick) of the
1984 NFL draft. He played three seasons for the Bears from 1984 to 1986, appearing in 25 games, none as a starter. He was also a member of the "Shuffling Crew" in the video
The Super Bowl Shuffle. He spent most of the
1986 NFL season on injured reserve after suffering a foot injury in preseason training camp. He was reactivated at the end of November and appeared in four games. In August 1987, the Bears traded Humphries to the
Denver Broncos in exchange for punter
Bryan Wagner. He appeared in seven games, all as the Broncos' starting right guard, during the
1987 NFL season. He appeared in only one game for the Broncos in 1988, having been placed on injured reserve status after the first game of the season. In August 1989, the Broncos announced Humphries' retirement. ==Later years==
