MMAjunkie was first to confirm the news with sources close to the bout and both Brown and Johnson have been dropped from the event’s official card.
Johnson withdrew from the 170-pound bout on Tuesday after suffering a knee injury in training.
Brown and Johnson’s exit from the card opens up a fifth slot on the Spike TV broadcast main card, which currently features The Ultimate Fighter 9 lightweight and welterweight finals, Clay Guida vs. Diego Sanchez, and Nate Diaz vs. Joe Stevenson. Unless another main card worthy bout is booked before the June 20 event in Las Vegas, Kevin Burns vs. Chris Lytle or Melvin Guillard vs. Gleison Tibau is likely to be bumped up to the main card.
