He won a silver medal over 60 metres at the 2003 IAAF World Indoor Championships, before going on to take his outdoor crown.

A dispute with the Saint Kitts and Nevis administrators saw Collins dropped from the 2012 Olympic Games and he did not return to international duty until 2015.

With Olympic and World Champion Maurice Greene eliminated in the semi-finals, the field was wide open.

In a very close race, where the top four athletes finished within 0.02 seconds, Collins won and became the first world champion from Saint Kitts and Nevis.

At the 2005 World Championships, Collins claimed a bronze medal in the 100 m behind Justin Gatlin and Michael Frater though he was given the same time as the latter.

He competed at the 2009 World Championships and reached the quarter-finals of the competition, but he was eliminated after finishing in fourth place behind eventual finalists Asafa Powell, Darvis Patton and Marc Burns.

[10] Collins returned to athletics on 29 January 2011 at the Aviva International Match in Glasgow, reversing his retirement at the age of 34, and he finished fourth in the 200 metres.

[13] Collins won both his heat and semi-final races in the 100m at the 2011 World Championships before finishing third and winning a bronze medal in the final after the disqualification of Usain Bolt.

The last event saw Collins team up with Jason Rogers, Antoine Adams and Brijesh Lawrence to clock 38.49 to win the bronze medal.

[16][17] Collins was expelled by his team from the 2012 Summer Olympics in London on 4 August 2012 for missing training sessions.

While most sprinters peak in their 20s, Collins set his personal record after reaching the age of 40, and became the first individual to run a sub-10 second 100 m dash in the process.
