UFC on FOX 4 is expected to be August 4th at the Staples Center in Los Angeles, CA. A heavyweight matchup has just been added to that card.
Ben Rothwell vs. Travis Browne will be on the main card of the event. Rothwell is coming off a knockout of the night performance over Brendan Schaub at UFC 145. Browne has still yet to lose a fight after his 1st round submission of Chad Griggs at the same event.
