Check out the video above and the play-by-play below:
R1: Sanchez lands a left round kick to the body, then a glancing uppercut. Now a lead left to the body for Sanchez. Lauzon wades forward in a low stance, winging wide heaters with both hands. A left hook catches Sanchez square and drops him. Lauzon stays on the trigger and wobbles Sanchez with another, though he's still on his feet. Sanchez tries to circle out and get some space but blatantly staggers away, clearly out of sorts. The ref steps in and waves it off.
