So I get up and I'm pissed. I'm yelling "What are you doing? I'm filling in trying to help you get ready and help you train, and you knee me in the back of the head?" So I'm going on and on and my coach calls me over and goes, "Uh Nick, you shot in and he just kind of back-handed you on the side of the head. It wasn't a knee and it wasn't even that hard." So I'm like, "Well, that will be the end of me sparring with Brock Lesnar." (laughs)

Thompson On Brock Lesnar's Chances Against Frank Mir:

I don't like the matchup for a wrestler's second matchup. Mir is a former world champion and he's got good jiu-jitsu. And traditionally that's not someone you want a wrestler going against. That being said, I've never seen someone as athletic, a big man as athletic -- frankly, anyone as athletic as Brock, much less a heavyweight.

And I think the thing that has really impressed me about Lesnar is normally when someone with his credentials comes into a gym, they usually want to do things their way and they don't really listen. He's been the complete opposite. He came in and said, "I want to learn. I'm a blank slate, teach me." And think if you combine his athleticism with his wrestling background and with that attitude and I really think he's going to go far in this sport. I think that begins on February 2.
