In a long rollercoaster career that has been blighted by drug addiction and almost constant legal troubles, McCall has served as the chief sparring partner for a peak Mike Tyson, then later came into his own as a professional, defeating Lennox Lewis, Larry Holmes, Lionel Butler, Bruce Seldon, Jesse Ferguson, Francesco Damiani, Oleg Maskaev, Henry Akinwande, Przemyslaw Saleta, Sinan Samil Sam, and Fres Oquendo.
McCall had a strong amateur career prior to turning pro, twice a winner of the Chicago Golden Gloves.
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 Bruce Seldon and lost a very close decision to Tony Tucker before landing the shot against Lewis in 1994.
McCall KOs Lewis
After a close first round McCall came out aggressive in the second and landed a big right hand as Lewis was coming forward, Lewis dropped to the canvas and got up before the count of ten, but he was unsteady on his feet, forcing the referee to wave a stop to the fight.
McCall successfully defended the title in a bout against 45 year old ex-champ Larry Holmes in Las Vegas winning 115-112 115-114 and 114-113 on the score cards, before returning to London to face Frank Bruno in 1995.
Losing the Title
McCall travelled to London to defend his title against Frank Bruno in 1995. Bruno started off well, working behind the jab and landing some big right hands. By round 9 Bruno had built up a big lead on the score cards and looked comfortably in charge. McCall landed several big punches over the final 3 rounds but his efforts were not enough as McCall lost the fight - and the title - to Frank Bruno.
McCall returned to the ring 6 months after losing his title. He beat future WBC heavyweight champion Oleg Maskaev in less than 3 minutes, and then a month later beat James Stanton in 6 rounds.
Bizarre Rematch with Lewis
Lewis and McCall squared off again on February 7, 1997, in Las Vegas. In a bizarre fight, McCall refused to fight in the fourth and fifth rounds, beginning to cry profusely and eventually forcing the referee to stop the fight and award Lewis the victory.
In 2001 at the age of 36 he resurrected his career with a tenth round knockout of Henry Akinwande, at the time one of the most avoided contenders in the world. McCall was ranked number 4 in the world off this performance, but was arrested shortly afterwards and imprisoned for over a year, losing his ranking.
Despite his legal troubles, Oliver's career has since continued. He began his next run at a title with a first round TKO of Kenny Craven in June 2006. McCall also defeated Darroll Wilson in a fourth-round TKO in Louisville, Kentucky.
More McCall Upsets
On 16 June 2007, McCall defeated Sinan Samil Sam for the WBC International Heavyweight Championship by unanimous decision in Ankara, Turkey. This guaranteed him a shot at the WBC Heavyweight Championship (currently held by Vitali Klitschko). However, McCall took a fight with slick Cuban fighter Juan Carlos Gomez, a fight which McCall originally lost before the ruling was changed to a No Conest after Gomez tested positive for an illegal substance after the bout.
In 2010, McCall took a split decision over Fres Oqendo (then 32-6) who was favorited against him.
McCall spent many years as a sparring partner for Mike Tyson.
After 60+ fights, McCall has still ever knocked down as a professional
In one of the most bizarre scenes in boxing history, McCall appeared to have a psychological breakdown in the ring during his rematch with Lennnox Lewis for a share of the heavyweight title.
McCall's career has been mottled by several stints in drug rehabilitation facilities and arrests for disorderly behavior.
