Unpredictability is a main factor to what draws people to the UFC, and that was on full display on Saturday at UFC Fight Night 106.

The co-main event spot became the highlight of the night when Edson Barboza landed a perfectly timed knee on Benil Dariush in the second round. Dariush made his mistake when he attempted a takedown after throwing a jab and was surprised and put straight to sleep by the explosive Barboza.
