Guillermo “Felino” Jones’ has until Thursday to select a date, set for next week, to have the Swiss Laboratory open the "B" sample of his drug test for the recently canceled rematch with Denis Lebedev (on April 25). Prior to that fight, samples were taken and analyzed by Switzerland's Swiss Laboratory for Doping Analyses (LAD). Jones' 'A' sample test positive for banned weight cutting agent Furosemide, the same substance which Jones tested positive for after knocking out Lebedev in 2013.

Jones has been given a choice of next Tuesday or Thursday. If Jones fails to select a date, then the Swiss Laboratory will conduct the test next Tuesday.
