A bout between Junior Dos Santos and Stipe Miocic will be moved from UFC 175 and will now headline UFC Fight Night 42, also a bout between Chael Sonnen and Wanderlei Silva will not be moved from UFC Fight Night 42 to the UFC 175 card. UFC officials have not given a reason for the card changes, but it may have been done to give more star power to the UFC 175 card.
