September 14, 1974 on "ABC's Wide World of Entertainment" promoter Mike Anderson introduced PKA 'full-contact' karate. In the bouts, competitors wore foam hand and foot protection and fought to the knockout (Kickboxing rules allowed for leg kicks: full-contact karate rules did not permit kicks to the legs). Lewis, the retired US Heavyweight Kickboxing champion was accustomed to full contact fighting. In 1974 he beat his only opponent in the new sport of full contact karate with a 2nd round ridge hand knockout over Yugoslavia's Frank Brodar in Los Angeles, California to win the Professional Karate Association (PKA) Heavyweight full-contact karate title.
