After playing college football for Baylor University, Singletary was drafted by the Chicago Bears in the 2nd round of the 1981 NFL Draft and was known as "The Heart of the Defense" for the Chicago Bears' Monsters of the Midway in the mid-1980s. He was inducted into the Pro Football Hall of Fame in 1998. Singletary later pursued a career as a coach, first as a linebackers coach for the Baltimore Ravens, then as the linebackers coach for the San Francisco 49ers.
