John Howard and Anthony Johnson will have to settle their beef another day. Same goes for Martin Kampmann who got into it with Diego Sanchez on Twitter earlier this week. Reason being: Howard and Kampmann have been scheduled to meet on the upcoming UFC on Versus 4 card which takes place in Pittsburgh on June 26.

UFC President Dana White has announced perhaps the most explosive matchup of the early summer, as two welterweight contenders collide in Pittsburgh on June 26th.

“Verbal agreements are in for a battle between two of the best strikers in the welterweight division as John “Doomsday” Howard takes on Martin “The Hitman” Kampmann,” said White.

That wasn’t the only fight announced for the Versus 4 card in recent days. Several others were as well, plus a few other summer match-ups.
