The most significant fighter to be felled by injury is Martin Kampmann, who is pulling out of his June 26th welterweight clash with John Howard at UFC on Versus 4. Matt Brown will move up from the undercard to face Howard, while Brown's original opponent, Rich Attonito, will now make his welterweight debut against Daniel Roberts. One could argue that "Doomsday" has caught a bit of a break here, given that Kampmann would have been an extremely tough test for him, but Matt Brown has certainly proven before to be a dangerous underdog.
Just to recap the changes, here are the new bouts:
