Conor McGregor suffering a broken toe during the final weeks of his training camp forced a dramatic shift in the UFC 303 main event with light heavyweight champion Alex Pereira stepping up on short notice to save the day in a rematch against Jiri Prochazka.
Of course it was well documented that Pereira actually suffered a broken toe of his own prior to his previous fight at UFC 300 but he remained on the historic card and ultimately knocked out Jamahal Hill in the first round.
