Richard John "Ricky" Hatton MBE (born 6 October 1978, Stockport, Greater Manchester, England), is a retired British professional boxer and a current boxing promoter.

He is a former WBA (Super), IBF & The Ring Light Welterweight Champion and WBA Welterweight Champion. After losing his last fight to Manny Pacquiao, Hatton put his career on a long hiatus, with rumours of a comeback circulating the media since. However, on 7 July 2011, Hatton announced his retirement from boxing.

Born in Stockport, Hatton was raised on the Hattersley council estate in Hyde, Greater Manchester and trained at the Sale West ABC (Racecourse Estate). He was educated at Hattersley High School. His grandfather and his father both played for Rochdale and Ricky had a trial for the youth team. He found a local boxing club in Hyde to train at. His entrance music is the Manchester City club song "Blue Moon", as performed by the band "Supra." Aged 14, Hatton was taken by his uncles Ged and Paul to Manchester United's Old Trafford stadium to watch the second fight between Nigel Benn and Chris Eubank. He joined the family carpet business on leaving school, but after he cut four of his fingers with a Stanley knife, his father made him a salesman to prevent him from losing his fingers.

Konstantin Borisovich "Kostya" Tszyu (/ˈkɒstə ˈzuː/; Russian: Константин (Костя) Борисович Цзю; born 19 September 1969) is a semi-retired Russian-Australian professional boxer of mixed Russian, Korean and Mongol descent. He holds both Russian and Australian citizenship and is a four-time world Light Welterweight Champion, including a period of time as the Undisputed Light Welterweight Champion.

Tszyu was the first champion to unify the light welterweight division in over 30 years. He is considered by many in Australia to be a national sports hero. On 7 December 2010, he was inducted in the prestigious International Boxing Hall of Fame for the Class of 2011.

As the son of his Korean (paternal) and Mongol (maternal) descent father, a fitter in a metal factory, and his Russian mother, a nurse, Tszyu was born in Serov, a town near the Ural Mountains, in the former Soviet Union.

Hyperactive as a child, his father decided to take him to a boxing gym, where he would channel that energy by fighting older boys.^{[citation needed]} He impressed Russia's amateur team coaches and he was sent to the Soviet Union's amateur boxing travelling training camps, where he was able to visit more than 30 countries while training and fighting in tournaments. He trained with that group 250 days a year, and won various tournaments, such as amateur boxing's world championships. He also participated in the 1988 Olympic Games. At the Cuban world championship tournament in 1987, he came in second place, and at the Seoul Olympic games, he lost in the third round.

Luis Collazo (born April 22, 1981 in Brooklyn, New York) is a boxer in the welterweight division. His boxing record is 31-4 (16 KOs). He is a former WBA welterweight champion.

He grew up in Brooklyn on Georgia Avenue and attended P.S. 290 and I.S. 302. He is of Puerto Rican descent. Collazo won the WBA Welterweight title on April 2, 2005 with a 12-round split decision victory over defending champion Jose Antonio Rivera. However, the WBA had elevated Cory Spinks to "Undisputed Champion" status before he had lost his titles to Zab Judah, so Collazo was not the definite champion of that organization. On January 7, 2006, Judah lost a 12-round decision to Carlos Baldomir in New York. Baldomir had chosen to pay the sanctioning fee of the WBC only; as a result Judah's WBA undisputed title was vacated. With Judah's loss, Collazo then attained recognition as the WBA's sole welterweight champion. On May 13, 2006, he lost the title to Ricky Hatton in a very tight affair which went the distance. On February 10, 2007 he lost a 12 round unanimous decision versus Sugar Shane Mosley in which he injured his hand early in the fight and continued on till the end. After working back from the injury through rehab and aggressive training, by long-time trainer Nirmal Lorick, Luis fought on the Roy Jones Jr vs. Félix Trinidad card, January 19, 2008 at Madison Square Gardens. He won a one-sided victory against Edvan Dos Santos Barros (9-5-1, 7 KOs), winning 100-90 on 2 judges' scorecards and 99-91 on the other.
