Magri was 5 ft 3 in tall and had an exciting, aggressive style, being a two-handed puncher who did not care much for defence. He was managed by
Terry Lawless. While working as a tailor's cutter by day, he had his first professional fight in October 1977, at the age of twenty-one; He knocked out Neil Mclaughlin in the second round at the
Royal Albert Hall. In only his third fight he gained the vacant British flyweight title after his fight with Dave Smith was stopped in the seventh round, equalling Dick Smith's 63-year old record for becoming British champion in the fewest fights. In December 1977 he was voted Best Young Boxer by the Boxing Writers' Club. In his twelfth fight, in May 1979, having won the previous eleven, he won on points against
Franco Udella to take the European flyweight title. He won on points over twelve rounds at
Wembley Arena. In December 1979, he defended his European title against Manuel Carrasco, of Spain, winning on points. In June 1980, he defended it again, this time against Giovanni Camputaro of Italy, winning on a technical knockout in the third. In September he fought a re-match with Rodríguez in
Avilés, Spain, and again knocked him out in the second.
World title In March 1983, he fought
Eleoncio Mercedes, of the
Dominican Republic, for the
WBC and lineal flyweight titles. The fight was at
Wembley Arena and Magri won the titles when the fight was stopped in the seventh on cuts. In September 1983, he defended his world titles against
Frank Cedeno, of the
Philippines. The fight was at
Wembley Arena, and Magri lost his titles when the referee stopped the fight in the sixth, after Magri had been knocked down three times. In October 1985, Magri fought a re-match against
Franco Cherchi, in
Alessandria, Italy, winning by a knockout in the second round. In May 1986, Magri had his last fight, defending his European title against
Duke McKenzie of
Croydon. Magri had relinquished his British flyweight title in August 1981, and McKenzie was now the holder. The fight was stopped in the fifth round when Magri was knocked down and his manager, Lawless, threw in the towel when Magri beat the count. ==Professional boxing record==
