Frank Tate vs. Michael Nunn, billed as Power Struggle, was a professional boxing match contested on July 28, 1988, for the IBF middleweight title.

[1] In April 1988, reigning IBF middleweight champion Frank Tate and the number-one ranked contender Michael Nunn had agreed to terms to fight one another in July of that year.

The bout had been in the making since Tate had won the title the previous October, but Tate put off facing the top-ranked Nunn, going as far as to refuse a reported $300,000 payday from Nunn's promoter Bob Arum, and instead made his first defense as the lower-regarded Tony Sibson.

[2] Nunn had officially become Tate's mandatory challenger after knocking out Curtis Parker in the second round of an eliminator bout in March 1988.

Nunn started the ninth aggressively and sent Tate back into the ropes with a series of punches to the head.
