Jones is officially back in the UFC as of today eligible to fight asap. But he has been given a "firm finger waggle" and "you better watch it or else" threat.
From UFC:
"Following a review of the plea agreement reached by Jon Jones and officials in Albuquerque, New Mexico, and the judge’s decision, UFC announced today the formal reinstatement of Jones to the UFC roster. Effectively immediately, Jones is eligible to return to competition. As such, UFC expects Jones to meet all of the terms of his plea agreement, including mandatory community service, as a condition of his reinstatement."
“We've made it clear to Jon that this new opportunity to compete in UFC is a privilege and not a right, and that there are significant expectations we have regarding his conduct moving forward," said UFC Chairman and CEO Lorenzo Fertitta."
