Michael Nunn vs. James Toney, billed as Rumble on the Riverbank, was a professional boxing match contested on May 10, 1991, for the IBF middleweight title.

[1] In the midst of a near three-year reign as the IBF middleweight champion, Michael Nunn, with help from his promoter Bob Arum, successfully lobbied for and received a chance to defend his title in his hometown of Davenport, Iowa.

[3] Nunn admitted at the pre-fight press conference that bringing a title fight to his native city "meant the world" to him.

Instead, minor league baseball team Quad Cities River Bandits' home ballpark John O'Donnell Stadium was chosen as it was determined to be the only venue big enough to accommodate the fight.

After the knockdown, Nelson stopped the fight just as Nunn's trainer Angelo Dundee threw in the white towel to signify surrender.
