They already pulled him from the card, there's a zero percent chance he fights on Saturday. USADA is going to review his case, but more then likely it's going to be a long time before we see Jones fight again.
This is a USADA decision, there's nothing the UFC can do about it.
UFC were so stupid for bringing USADA into their organization. They really thought this wouldn't happen? The NFL would be shut down in two years from too many test failures if they brought USADA testing in.
LET THEM USE THEIR ROIDS .
