The Ultimate Fighting Championship has reportedly shifted around a couple of key fights, and as a result, Chael Sonnen will no longer fight Wanderlei Silva in Brazil.

Sonnen and Silva, who coached opposite one another on the latest season of TUF Brazil, were expected to square off May 31st in Sao Paolo. According to a report from Yahoo’s Kevin Iole, however, that light-heavyweight fight has been moved to UFC 175.

The July 5th card will take place at the Mandalay Bay Events Center in Las Vegas. Silva-Sonnen will serve as the co-main event. Middleweight champion Chris Weidman is scheduled to fight Lyoto Machida in the headliner.

Moving to the May 31st, Fight Night card is a heavyweight bout between Junior dos Santos and Stipe Miocic.  That bout was originally scheduled to take place May 24th at UFC 173. The headliner for the Las Vegas bound event will see bantamweight champ Renan Barao take on TJ Dillashaw.
