Maurico ?Shogun? Rua vs. Brandon Vera is the new main event for UFC on Fox 4

A shoulder injury to Brian Stann forced big changes for the UFC's next event on Fox. Now, instead of Stann facing former Bellator champ Hector Lombard, the main event will feature a light heavyweight match-up. Former champion Maurico "Shogun" Rua will take on Brandon Vera on Aug. 4 in Los Angeles.

Rua was supposed to fight Thiago Silva in July, but that bout was scrapped because of an injury to Silva. Vera was training for a fight with James Te Huna earlier in July, but Te Huna now needs a new opponent.

Lombard is opponentless. With the UFC so packed with fights over the summer, there aren't many healthy middleweights available to take on Lombard in his UFC debut. The UFC just had to juggle middleweights around to handle Vitor Belfort's injury and removal from the UFC 147 main event.
