'Extremely competitive'. Nickal is ready to have a grappler fight with Khabib

"Yeah, grappling rules are a completely different, feisty game. I think it would be extremely competitive and would probably be the best set of rules for us to compete against each other. It would be a lot of fun. He's a great fighter and a tremendous talent. I think obviously I have the wrestling advantage and if it was a Sambo competition, you have to give the advantage to him, but grappling would probably be the most competitive scenario, it would be fun."
