In 1982, McGuigan won eight fights, seven by knockout. One of these, however, almost destroyed his career and his life. Opposed by Young Ali, on 14 June 1982, McGuigan won by a knockout in six rounds; Ali fell into a coma from which he never recovered. According to the book "The Ring: Boxing The 20th Century", this affected McGuigan so much he was not sure he wanted to carry on as a boxer. He also defeated Paul Huggins and Angelo Licata during this period. In 1983, he won four fights, winning the British Title against Vernon Penprase, and including his first trip to fight outside Europe (when he beat Lavon McGowan by a knockout in the first round in Chicago), before getting his first try at a European title.
