Fans will have to wait a little longer to see Alistair Overeem vs. Junior dos Santos.According to sources close to Overeem, the heavyweight recently suffered an undisclosed injury while training, which will sideline him for four-to-five weeks. As a result, Overeem’s camp recently informed the UFC that he will be unable to fight dos Santos at UFC 160 on May 25. Overeem is hoping to return to action against dos Santos in July, but as of right now, no decision has been made when he’ll return and against who. Also, no word just yet on if dos Santos will remain on the UFC 160 card and fight someone else or wait for Overeem return.
