Marcin Tybura puts Tai Tuivasa to sleep in heavyweight stunner

UFC Vegas 88 took place on Saturday at the UFC APEX in Las Vegas, NV., and delivered a monstrous heavyweight main event. 

Headlining the card was No. 9-ranked Tai Tuivasa, who was on a three-fight losing streak. Unfortunately, it wasn't his night. 

Tenth-ranked Tybura was able to get out of early danger and took Tuivasa to the canvas where he issued nasty ground and pound to take Tuivasa's back and secure the rear-naked choke for the submission win. The finish came in the very first round and Tuivasa was out cold. 

In the co-main event, Bryan Battle and Ange Loosa ended in a no contest when Loosa suffered an eye poke and could not continue fighting. After the fight was called, Batlle and Loosa exchanged words and had to be separated.
