Building off his real-life persona, Liddell will play a mixed martial artist considered to be the toughest guy in the world. However, his connection to the case of the week will provide some interaction with Booth (David Boreanaz). Given that Booth is on the hunt for Pelant (Andrew Leeds) this season, perhaps Liddell's character could give Seeley a few tips on how to inflict some pain?

Since his days as UFC Light Heavyweight Champion, "The Iceman" has appeared on such shows as Entourage, Blue Mountain State and Hawaii Five-0. He also competed on the ninth season of ABC's Dancing with the Stars.
