Former Ultimate Fighting Championship (UFC) light heavyweight champion Jon Jones, who was arrested and charged with alleged felony hit-and-run back in April, will not appear before a grand jury because the 60-day deadline to make it happen expires today.

Whoops.

Turns out the prosecution is still missing two key pieces of evidence. In addition to the medical records for the injured victim, dispatch reports from the Albuquerque Police Department are still outstanding. That means Jones is no longer bound by the conditions of his release.

"Proceeding on a case without complete discovery could result in the likely dismissal of the case altogether," district attorney Public Information Officer Kayla Anderson told MMA Junkie. "We have requested both pieces of outstanding evidence and anticipate moving forward when we have a completed case investigation."

That means Jones, who could end up in the slammer, may still have to face the music later this year.

"Bones" was stripped of his 205-pound title and suspended from the world's largest mixed martial arts (MMA) promotion, which continues to create distance between itself and its former pound-for-pound king. That includes the crowning of a new light heavyweight champion, which was not well received by some folks in the combat sports community.

It will be interesting to see how the next few weeks play out. In the meantime, get up to date on everything relating to Jones' recent arrest right here.
