VIDEO: Craig Jones Outclasses Kevin Casey at Submission Underground 12 With Deadly Heel Hook

Kevin Casey said uncle. In the main event as Chael Sonnen's Submission Underground 12 event in Portland, Oregon on Sunday -- yes, there were live sports on this weekend! -- grappling virtuoso Craig Jones showed his class, rolling challenger Kevin Casey into a heel hook and forcing him to submit.

Curiously, Casey gave up verbally instead of tapping out. Of course, the result was the same. Jones reigned supreme, wrapping up the day's action with a convincing performance that simply left no doubt.

So, how much longer do we have to wait for more submission grappling, or perhaps (god forbid!) mixed martial arts? We'll wait. We've got plenty of time.
