BEIJING, China:

IT has been confirmed that Jamaica will only be allowed to enter three sprinters in the men's 100m after Nesta Carter's submission as a replacement for the injured Kemar Bailey-Cole was rejected by the International Association of Athletics Federations (IAAF) technical delegate at the World Championships.

It's a decision that has left members of Jamaica's management team scraping for answers after what was expected to be a straight-forward adjustment.

The Jamaicans had hoped that Carter, who finished fourth at the Jamaica Athletics Administrative Association (JAAA) Supreme Ventures Limited National Senior Championships, would be allowed to join wild-card entrant Usain Bolt, Asafa Powell and Nickel Ashmeade in the men's 100m after Bailey-Cole suffered a hamstring injury during a pre-championships camp in Tottori, Japan.

However, JAAA general secretary and newly elected member of the IAAF's Technical Committee, Garth Gayle, told Jamaican journalists that the IAAF would not allow Carter to be substituted into the field, noting at the time that no clear reasons were given for their decision.

Jamaica were allowed four entrants given Usain Bolt's wild-card entry as defending world champion.

"The IAAF has denied Jamaica its right for a substitution according to the IAAF rules and I find that difficult to accept and I have been vigorously seeking an answer.

"The response has not been pleasing and is not within the spirit of the competition, where a country is now being denied one of their legitimate entries when we are seeking simply a substitution," said Gayle.

"All I was told is that the technical delegate has ruled on the matter and that is unacceptable," Gayle said.

Team manager Ludlow Watts said he was surprised and confused by the decision, given that the rules allow for adjustments to be made before 24 hours of the competition.

STAR Sports has not been able to confirm whether or not Carter's entry was submitted within the specified time frame or if there were any other issues with his entry.

At the 2011 World Championships in Daegu, South Korea, Carter was allowed to be added to the team after Asafa Powell was forced to withdraw due to injury.
