Travis Browne's loss is a pair of welterweights' gain.
According to the UFC on FOX Twitter account, Browne has been removed from the Aug. 4 card, while Mike Swick vs. DaMarques Johnson has been bumped up to the main card. In the end, while names like Devin Cole and Matt Mitrione were discussed, the UFC could not find a suitable opponent for Browne.
Swick (14-4) hasn't fought since his loss to Paulo Thiago at UFC 109 in Feb. 2010. A serious stomach ailment and a knee injury kept him out of the Octagon for over two years.
Johnson (16-10) lost to John Maguire in his last fight via second-round armbar submission.
UFC on FOX 4, headlined by Shogun Rua vs. Brandon Vera, will air on FOX from the Staples Center in Los Angeles next Saturday night.
