I am glad you are looking him up. He is one of those athletes that doesn't give up.
There are quite a few matches of his available on YouTube. His most popular feud has been with Jerry Lawler. That has been going on for years now and only getting better.
I first saw Matt in action at an event locally involving Jay Lethal. Being completely new to the local wrestling scene I was there to see Lethal. I came away a fan of Riviera and several others.
