Judge Michael Martinez has ruled that former UFC champ Jon Jones will be able to fight at UFC 197 in Las Vegas on April 23. Jones spent a night in jail for probation violation after being pulled over and accused of drag racing.

The Bernalillo County District Attorney had sought "to have Jones' probation revoked and then reinstated with three new conditions: Jones completes a driver improvement course; he agrees to a curfew; and he enrolls in and completes an anger management counseling course" according to MMA Fighting.

The judge declined to impose a curfew after his defense argued it would impede his ability to travel to Las Vegas for the title fight. However Jones is not permitted to drive without the permission of his probation officer, and Martinez warned Jones that another court appearance "won't end well" for him.

Jon has been released following a night in jail.

Jones is on probation after a conviction for a hit-and-run last year that resulted in injuries to a pregnant woman and Jones being stripped of his UFC title. UFC 197 will mark his return to the Octagon.
