Jon Jones doping case: What we know so far

Jon Jones' current fight is taking place inside laboratories and administrative buildings.

MMA's pound-for-pound king tested positive for two banned substance before UFC 200 and was pulled from the card just three days before his main event title fight against Daniel Cormier was supposed to go off. Now, Jones will have to go through the appeal process with both USADA, the UFC's anti-doping partner, and the Nevada Athletic Commission (NAC).

On Monday, the NAC released the names of the two substances found in Jones' system in the June 16 sample collected by USADA: hydroxy-clomiphene (or Clomid) and Letrozole.
