Lewis died in Phoenix, Arizona and the cause of death has not been specified at this time.
Lewis, an Ohio native, played his college ball at Northern Arizona University from 1992-1995, and was most recently working as the school's wide receivers coach.
After leaving NAU in 1995, the Broncos selected Lewis in the fourth round of the 1996 NFL Draft to backup, and possibly one day succeed Denver legend John Elway. Lewis remained with the team as the third string QB for two seasons, winning a ring for Super Bowl XXXII.
He was released from the Broncos in 1998, joining the Carolina Panthers from 1999-2000, and was a member of the New Orleans Saints practice squad in 2002 before leaving the NFL.
“We are deeply saddened by the death of former Broncos quarterback Jeff Lewis,'' the Broncos said in a statement. ''Our most heartfelt condolences and prayers go out to Jeff's family and friends.''
Lewis was named to the NAU Hall of Fame in 2003.
