A potential title eliminator in the lightweight division as former UFC Lightweight Champion Ben Henderson faces former Strikeforce Lightweight Champion Josh Thomson. Henderson will be fighting for the first time since he lost the UFC Lightweight Title to Anthony Pettis at UFC 164. Thomson was originally set to fight Anthony Pettis for the belt at UFC On Fox IX, but an injury to the champion scrapped those plans. UFC On Fox X takes place on January 25th from the United Center in Chicago, Illinois with the aforementioned fighters headlining.
