In 1973, Lovell was stunningly upset by Texan knockout king Terry Krueger. Lovell had been winning the fight. He bloodied Krueger’s nose and seemed headed for an easy stoppage. However, Krueger let go with a wild left hook, and Pedro Lovell’s undefeated streak ended. He was unconscious for more than three minutes. 
A few months later the pair were rematched, and Lovell broke Krueger’s jaw on the way to scoring three knockdowns and a first round victory. Lovell went on to destroy former heavyweight contender Billy Daniels in one round.
