[Q]: Passage: He began his career with local side Leeds United in 1984, before he moved on to Hull City for £200,000 in 1989. Two years later he transferred to Port Vale for a fee of £300,000. He spent three years with Vale, before he was sold on to Plymouth Argyle for the same price. During his time at Vale Park he was selected in the PFA's Second Division team of the season in 1992–93, before he won promotion out of the division in 1993–94; he also won the TNT Tournament in 1992 and the Football League Trophy in 1993 with the club. However at Plymouth he failed to find success, and was instead transferred to Burnley for £200,000 after just twelve months. In 1997, he signed with Bury for £50,000, before he returned to Burnley as a free transfer signing the following year. In 2000, he joined York City, before he retired later in the year.

[Q]: Passage: De León, a native of Trujillo Alto, Puerto Rico, first won a world title when faced with WBC world champion Marvin Camel on November 25, 1980, at the undercard of Sugar Ray Leonard and Roberto Durán's second fight in New Orleans. De León outpointed Camel over 15 rounds. After he knocked out Camel in 8 in a rematch, countryman Ossie Ocasio won the WBA world title, becoming the second pair of Puerto Ricans to share world titles in the same division at the same time, after Alfredo Escalera and Samuel Serrano had achieved the feat in the 1970s at Jr. Lightweight. De León lost his title in a shocking upset to former Gerry Cooney victim S. T. Gordon by a knockout in round 2 at Cleveland in 1982, and won a comeback fight versus former world Heavyweight champion Leon Spinks by a knockout in round six in 1983. After that, he and Gordon boxed a rematch in Las Vegas, and De León dropped Gordon once in the first round and once in the twelfth, en route to a unanimous decision win in a history-making bout: De León had now become the first boxer to win the world Cruiserweight title twice.
