Steve Collins, Irish boxer and actor
Stephen Collins (born 21 July 1964) is an Irish former professional boxer who competed from 1986 to 1997. Known as the Celtic Warrior, Collins is the most successful Irish boxer in recent professional boxing history, having held the WBO middleweight and super-middleweight titles simultaneously and never losing a fight as champion.

Collins' first nineteen professional fights all took place in the United States. In 1988 he won the Irish middleweight title, and the regional American USBA middleweight title the following year, defending the latter successfully in Atlantic City and Las Vegas. In his first two world championship challenges, both for the WBA middleweight title, Collins lost a unanimous decision to Mike McCallum in 1990 and a majority decision to Reggie Johnson in 1992. He also challenged unsuccessfully for the European middleweight title later in 1992, losing a split decision to Sumbu Kalambay in Italy.

It was not until Collins reached his early 30s that he fulfilled his potential, becoming WBO middleweight champion in his third world title attempt with a fifth-round TKO victory over Chris Pyatt in 1994, before then moving up in weight to defeat the undefeated Chris Eubank and claim the WBO super-middleweight title in 1995. More success followed, as Collins successfully defended his title by winning the rematch against Eubank later in the year. Collins successfully defended his title another six times before pulling out of a proposed fight in October 1997 against rising Welsh star, Joe Calzaghe, and retiring from the sport, with Collins frustrated by his inability to get a fight against the pound for pound number one boxer of the time, Roy Jones Jr., who was then fighting in the light-heavyweight division.

Having competed against some of the best boxers on both sides of the Atlantic during his career, Collins tends to be linked more to an era in the UK during which there was a notable rivalry between British boxers Chris Eubank and Nigel Benn, both of whom Collins fought and defeated twice.
