At "Submission Underground 2" this past weekend (Sun., Dec. 11, 2016) in Portland, Ore., former Ultimate Fighting Championship (UFC) Light Heavyweight champion Jon Jones made fairly easy work of Dan Henderson in the headlining match (recap here). After just a little more than six minutes of action, "Bones" locked in an air-tight arm triangle choke that forced "Hendo" to tap, capping off an impressive debut for Jones' grappling career. If you happened to miss the showdown -- which went down on FloGrappling.com — have a look at the match-ending submission courtesy of Jackson-Winkeljonh’s Instagram account in the embedded clip above. Enjoy!
