LAS VEGAS – If Stephen Thompson was ever going to announce that he had arrived, Saturday night was a good time to do it. His UFC 196 pay-per-view co-main event with Johny Hendricks became a UFC Fight Night main event on free television when the Cain Velasquez-Fabricio Werdum heavyweight title fight fell out. Hendricks was a former champion who was still positioned near the top of the division. And it was ripe set-up for a knockout artist like "Wonderboy" to prove that even the most infallible chins cave in behind his touch.
