Career
Corbett"s weight fluctuated significantly throughout his career and although he had some fights at both heavyweight and light-heavyweight, the bulk of his contests and his success came at cruiserweight. Corbett boxed for Ireland as an amateur before turning professional in December 1994, winning his first fight at the G-Mex Leisure Centre, Manchester, England, in which he knocked out Donaster"s David Jules on a card that included Eamonn Loughran and Chris Eubank. On 19 May 2009 he competed in the first cruiserweight instalment of the "Prizefighter" series, defeating the former Southern Area Heavyweight Champion Micky Steeds on a 3-round points decision in the quarter-finals before losing on a 2nd-Round stoppage to the unfancied Ovill McKenzie in the semi-finals.
He returned a year later for the second cruiserweight instalment of the "Prizefighter" series.
Okoth started the tournament as a reserve and only came into the tournament after an injury to Herbie Hide. Corbett returned in April 2012, losing over 6 rounds to Michael Sweeney.
