UFC superstar Jon Jones was arrested for DWI and a gun charge in New Mexico Thursday morning, TMZ Sports has confirmed.

Cops say they responded to reports of gunfire in Albuquerque at around 1 AM -- and when they arrived to the scene, they found Jones inside a 2019 Jeep with the engine running and the car in park.

Jon denied firing a gun -- but officers say he appeared intoxicated (bloodshot, watery eyes and reeked of booze) and conducted a field sobriety test, which he allegedly bombed.
