The UFC announced the late replacement for Jones on Thursday night, less than 48 hours before the mixed martial arts promotion’s biggest show of the summer.

The 41-year-old Silva (33-7) is one of the greatest fighters in the sport’s history, reigning as the middleweight champion for nearly seven years. But he hasn’t earned a victory in four fights since October 2012, enduring injuries and a doping suspension that invalidated his only win in that stretch.

Silva will step in against Cormier, the UFC’s vaunted 205-pound champion. Cormier’s rematch with Jones was canceled Wednesday night after Jones failed a doping test.

Silva also had surgery to remove his gall bladder just seven weeks ago.
