The World Anti-Doping Agency is planning a special visit to Jamaica next year in the wake of concerns over the Caribbean nation's anti-doping programs.

"WADA has accepted an invitation from the Prime Minister of Jamaica to visit and inspect JADCO (the Jamaica Anti-Doping Commission)," WADA said in a statement on Monday.

The visit follows comments by former JADCO executive director Renee Anne Shirley that there had been a significant gap in out-of-competition testing by JADCO in the months before the 2012 London Olympics, where Jamaican sprinters were dominant.
