(picture not from UFC 100)

C.B. Dollaway's old problem with Jiu-Jitsu reared their ugly head as the former The Ultimate Fighter season seven contestant was submitted by Tom Lawlor in under a minute. 

Dollaway started out with a little combination and then a takedown but Lawlor sunk in the guillotine choke on the take down and choked Dollaway until he passed out at the fifty-five second mark. 

In what will be remembered as one of the most bizarre entrances in UFC history, Tom Lawlor entered the Octagon to "Who let the Dog's out" with the much derided Seth Petruzelli on all fours, wearing a chain with a bone his in mouth. Memorable to say the least from a fighter who paid tribute to the Just Bleed Fan at the weigh-ins yesterday.
