As of this writing (5:30pm EST), former UFC champ Jon Jones is currently languishing in a jail cell. Why, you may ask? Well, remember those tickets he got for assorted driving-related violations the other day? When you’re on probation, that sort of thing is a no-no.

Here’s TMZ with the scoop:

Jon Jones was booked in New Mexico for violating his probation moments ago — and posed for a brand new mug shot after turning himself in … TMZ Sports has learned.

We’re told a judge had issued a warrant for the UFC star’s arrest for violating the terms of his probation after he was cited for drag racing in Albuquerque last week.

Jones was sentenced to probation last year after being convicted in a hit and run case in which the UFC star crashed into a pregnant woman’s car and then ran from the scene on foot.

One of the terms of Jones’ probation was to not get into any trouble with the law — and the judge felt the drag racing citation qualified as a violation.

Whether he gets out and faces major legal consequences or no legal consequences, one thing is sure: the UFC would be foolish for taking a risk on this guy staying out of trouble. And do we really need a champ who can’t defend the belt because he’s incarcerated?
