Free fight! Michael Johnson leg-folds Gleison Tibau with blistering UFC 168 knockout

I'm not sure what the official term is, but Gleison Tibau did that leg-fold thing where he got his clock cleaned by Michael Johnson, then fell backward onto his leg, which bent in the wrong direction before snapping back like it was launching an Angry Bird.

Looks painful.

But it was also a stark reminder that Johnson has knockout power, something Dustin Poirier will need to be weary of when they collide this Saturday night (Sept. 17, 2016) during their UFC Fight Night 94 main event, which takes place inside State Farm Arena in Hidalgo, Texas, live on FOX Sports 1.

That's just four days away.
