Bader (14-2) scored a huge win in his last fight at UFC 144 when he defeated Quinton Jackson by unanimous decision. With the exception of a big slam from Jackson in the fight's opening round, Bader was thoroughly in control as he scored numerous takedowns on his overweight foe.
Machida (17-3) hasn't been looking like the unbeatable "Dragon" of old. Machida sports a 1-3 record since losing his UFC light heavyweight title way back at UFC 113 to Mauricio Rua. Machida last fought Jon Jones at UFC 140 in an attempt to reclaim his belt. Despite initial success with a few punches finding their mark, Machida was caught in a standing guillotine choke in the second round which rendered him unconscious.
Machida's sole win in the 1-3 span comes from a highlight reel front kick knockout over Randy Couture at UFC 129.
UFC on Fox 4 is expected to take place on August 4 at Staples Center in Los Angeles, California
