Top ranked fighter “Filthy” Tom Lawlor broke his forearm this weekend and has subsequently been forced to withdraw from the World Heavyweight Championship Tournament.

Lawlor, who had advanced to the final four, was set to compete against Matt Riddle next Thursday in the semi-finals.  Instead, he is undergoing surgery in Las Vegas to have pins and a plate installed in his forearm.

With Lawlor officially out of the tournament, league officials are now in the process of activating one of the tournament alternates.

The question is who is the alternate?
