Oliver McCall Oliver McCall Oliver McCall (born April 21, 1965) is an American former professional boxer who competed from 1985 to 2014. He is best known for winning the WBC heavyweight title in 1994 by scoring an upset knockout victory over Lennox Lewis. The next year he defended the title against Larry Holmes before losing it to Frank Bruno. McCall would also become known for an in-ring mental breakdown during his 1997 rematch with Lewis. Known as "The Atomic Bull", McCall turned pro in 1985 and slowly worked his way up the heavyweight ranks. He beat Jesse Ferguson and future heavyweight champion
Frank Bruno Mike Tyson in his first defence. Tyson beat Bruno on a stoppage in round three, Bruno performing unusually poorly in what turned out to be his last bout as a professional, due to a severe eye injury caused by Tyson. Bruno was advised not to fight again to avoid running the risk of causing any more damage to it, which could result in permanent blindness. Bruno retired soon after the fight. Bruno's publicist throughout most of his career was sports historian Norman Giller, who wrote three books in harness with Frank: "Know What I Mean", "Eye of the Tiger" and
