Roy Nelson vs. Brendan Schaub
Round 1
Schaub comes out jabbing and Nelson wants no part of it. Nelson backs up to the cage and Schaub unloads with both hands. Nelson is able to block everything. Nelson closes in and trips Schaub to the floor. Nelson begins to work from half guard. He passes to side control and looks to set up a kimura on Schaub's left arm. Schaub spins out and stands. Schuab is swinging for the fences and Nelson briefly obliges his opponent. Schaub's jab is effective, but he leaves his hands down and is cracked by a Nelson right hook. Schaub bounces a sloppy left hook off the chin of Nelson. "Big Country" then steps forward in the pocket and outs Schaub's lights out with a right hook on the ear. Nelson hits him with a final right hand for good measure as referee Herb Dean steps in to save the sleeping fighter at 3:45 of the first. Roy Nelson has been crowned season 10 champion with the knockout.
