New title match as UFC on FOX main event

After TJ Grant pulled out of his scheduled lightweight title match with Anthony Pettis on 12/14 because he hadn't recovered fully enough from a concussion, it was announced tonight that Josh Thomson, the former Strikeforce champion, would be taking his place.

The 12/14 UFC on FOX show will be coming from Sacramento.

Who would you have the most interest in for Fabricio Werdum's next title defense?
