Michael Nunn vs. Marlon Starling was a professional boxing match contested on April 14, 1990, for the IBF middleweight title.

[1] In October 1989, the undefeated and reigning IBF middleweight champion Michael Nunn reached a multiyear agreement with the then-brand new Las Vegas area hotel and casino The Mirage that would see Nunn defend his title against a yet-to-be named opponent.

[5] Originally scheduled to take place on January 27, 1990, the fight was postponed after Nunn injured his back in December when he fell on steps as this home.

[6] As it was not known how long it would take for Nunn's injury to heal, a new date was not announced at the time of the postponement until over a month later when the fight was rescheduled for April 14.

[7] Starling, having made a 2-weight class jump and giving up six inches to Nunn, was a 6–1 underdog going into the fight.
