Lamar Clark, 183, West Jordan, Utah, stopped Eric (The Great) Forsland, 220, Salt Lake City, at 1:31 of the first round of a scheduled 8-rounder.
This wasn't boxing match, it was an exhibition.
Quote from fight description:
Source: AP, Reno Evening Gazette 12/27/1958Clark, who says he'll fight anybody for the experience, dazed Forsland with a left to start the fight. Forsland tried a pair of double-fisted ramrod punches and abandoned that in favor of about 60 seconds of grappling.
After Clark swatted him into the ropes, Forsland's ankles caught in the second and third strands and held him upside down with his head banging against the floor.
While he was in this ungainly position, he was counted out.
