It looks like UFC on Fox 8 will be featuring no fights at a higher weight class than middleweight now. Heavyweight Matt Mitrione was forced out of his grudge match with Brendan Schaub due to an injury, and he won't be replaced in the bout. Therefore, Schaub has been removed from the card as well. MMA Fighting has the news:
The heavyweight fight, which was scheduled to take place July 27 at UFC on FOX 8, has been pulled from the card after Mitrione suffered an injury in training, according to sources close to the fight. The same sources indicated that the UFC was leaning towards re-booking the fight on a later card, and as a result, they decided to pull Schaub from the event in Seattle altogether.
The two men, who used to be friends, engaged in a lengthy twitter battle last month to add some fuel to the fight. Neither man has said anything in regards to the fight being pushed back as of yet. Mitrione (6-2) is coming off a 19-second knockout of Phil De Fries in April, while Schaub (9-3) broke a two-fight losing streak with a victory over Lavar Johnson at UFC 157.
