Oh boy did the UFC Vegas 16 main card start with a nasty finish! At just 22-seconds into the opening round, undefeated lightweight Jordan Leavitt scored a brutal slamming knockout on Matt Wiman. This is a classic example of when pulling guard goes wrong, as Leavitt framed against Wiman’s face before slamming him into the mat, rendering the veteran unconscious. What an excellent technique to counter a guard pull, and quite a speedy way to end a fight! In a bit of a scary sight, the 37-year-old Wiman was down for some time before he was up and moving around.
