João Luiz Ramires Vieira, known as João Luiz (born December 20, 1985 in Brazil), is a footballer who currently plays as a midfielder for Beira Mar.

He made his debut for Marítimo on December 23, 2007 in a 2–1 away victory against União Leiria. His first and so far only goal for the club came in a 4–1 defeat of Sporting Braga at home on April 19, 2008.

Luisito Pio Espinosa (born June 26, 1967 in Manila) is a retired boxer from the Philippines who won World titles in two different weight divisions.

Espinosa turned professional in 1984. In 1989, he won the WBA Bantamweight title by knocking out Khaokor Galaxy in the first round. He was then managed by famed boxing analyst and businessman Hermie Rivera. Espinosa defended the title twice before losing it to Israel Contreras by a 5th round knockout in 1991.

Espinosa made an arduous climb back to the top, this time fighting under Joe Koizumi's stable. His comeback culminated in 1995, when he won the WBC Featherweight title by outpointing Manuel Medina. In his first title defense, Espinosa knocked out Alejandro "Cobrita" Gonzalez in the 4th round in Mexico. He then took on the hard-hitting body-puncher Cesar Soto at Luneta (Rizal) Park in Manila and hammered out a well-deserved unanimous decision in front of his countrymen, which included no less than President Fidel V. Ramos. He defended the title seven times before losing the belt in 1999 to Soto who won by a controversial unanimous decision. The following year, he challenged Guty Espadas Jr for the Vacant WBC Featherweight Title, but was outboxed and lost a technical decision after their fight was stopped after a clash of heads. Espinosa retired in 2005 after being knocked out by Cristobal Cruz.

Kennedy McKinney (born January 10, 1966 in Hernando, Mississippi) is a former professional boxer, who won the bantamweight gold medal at the 1988 Summer Olympics. As a professional, he won the IBF and WBO super bantamweight titles.

Known as "King", McKinney was a cautious yet exciting junior featherweight (super bantamweight) fighter who captured the IBF title by beating Welcome Ncita in 1992 in a spectacular bout that saw him on the deck before knocking the African cold with a perfect right hand.

After five defenses, among others a KO over Rudy Zavala and a points win over Ncita, he lost his belt to future star Vuyani Bungu, a fight which was deemed 1994 Upset of the Year by Ring Magazine.

Two years later he challenged undefeated Marco Antonio Barrera for the WBO super bantamweight title, a vicious battle in which he dropped Barrera in the 11th, but lost via TKO in the 12th. McKinney later took a rematch against Bungu, but lost a narrow split decision. Later that year, he did battle with Junior Jones who had upset Barrera in an exciting war, one which McKinney won via TKO.
