From my first book:

"Detroit Heat

The fifth and last round of the 1981 Bill “Caveman” Lee-John LoCicero fight in the suffocating heat at the Twenty Grand Showrooms in Detroit would give this short battle cult-like status.

LoCicero, who got decked early in the round, got up and pummeled the Caveman with between twenty and twenty-five unanswered and savage shots, including one of the biggest overhand rights I have ever witnessed. How Lee withstood this bombardment without going down remains a
mystery. However, when LoCicero got arm weary, the Caveman regrouped and took over pummeling LoCicero until he was knocked out in the same round. Lee was hurt in the fourth. Then, early in the fifth, LoCicero was almost out, then later Lee was almost out, and then LoCicero went down and out! This was Meza-Garza but longer.

The once-promising LoCicero would never be the same, losing three of his
next four fights before retiring. As for the Caveman, he would finish with a 23-4 slate (22 KOs). An exciting fighter, only two of his twenty-seven fights went the distance. One of his losses was to Marvelous Marvin Hagler in a 1982 title fight."
