Buckey attended St. Jago High School.[1] As a professional, he began with the MVP Track Club, then transitioned to the Racers Track Club, then returned to the MVP Track Club in 2012.[2]
He started his career in international athletics with an appearance at the 2004 World Junior Championships in Athletics. He set a personal best of 52.03seconds in the 400m hurdles heats, but was eliminated in the semi-finals. He took third place at the 2007 Jamaican National Championships, running a season's best of 49.24s behind Danny McFarlane and Isa Phillips.[3] This earned him the third spot on the Jamaican team at the 2007 World Championships in Athletics, but he did not managed to finish in his first race in Osaka, bringing an abrupt end to his senior global debut.[citation needed]
He made his Olympic debut the following year at the 2008 Summer Olympics and he set a personal best of 48.50seconds to qualify in the semi-finals. He was a little slower in the final race, however, and finished in seventh place. He ran at the 2008 IAAF World Athletics Final afterwards and took fourth place. He lost out on a place at the 2009 World Championships in Athletics to Josef Robertson, and Buckley missed the competition as an unused reserve athlete.[4]
