Check out Dallas Winston's play-by-play:
Round 5 - Immediate takedown from Johnson. Horiguchi trying to make something happen on the bottom but DJ's not having any of that. Hori got up, just to go back down. Sound familiar? Horiguchi gave up his back to spin away and get back to the feet, but DJ's all over him and gets him right back to the floor. This time against the cage. DJ passed to side. Knee to the body from DJ. Horiguchi back up. Body kick from Johnson. Back to the ground. Johnson trapped and arm and dropped a gaggle of punches, then spun to grab an armbar. He got Horiguchi to tap with one second to go! WOW! That's obviously the latest sub of all time. Wow.
