11:29 AM PT -- EAG Sports, which represents Jon, just issued a statement saying, "Jon and his team are taking this very seriously and we will let the legal process play out."
"We are confident he will be released once he has an opportunity to explain to the judge the facts in this case."
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.
Jones turned himself in to the Albuquerque PD at 10 AM Tuesday morning. He's currently being held at the county jail.
