Sonny Liston -vs- Gene Tunney

Liston didn't stop Whitehurst, but in their a second fight he came pretty close.

"Whitehurst was knocked through the ropes in the final seconds of the fight. The Associated Press reported: "In a wild flurry of lefts and rights, Liston sent Whitehurst reeling through the ropes. Whitehurst lay on the apron as referee Harry Kessler began his count. He was trying to get back in the ring when the final gong sounded at the count of eight."

 

If Tunney beat Liston in this fight...it wouldn't surprise me.
