UFC president Dana White told reporters following the UFC 152 post-fight press conference that MacDonald suffered a large cut in training above his left eye and will be unable to recover in time to compete at the Sept. 22 event in Toronto, Ontario, Canada.
White said he does know know if Penn will remain on the card and if he does, it is unknown at this time who the former welterweight and lightweight champion will compete against.
According to White, MacDonald needed over 40 stitches to close the wound.
MacDonald last fought at UFC 145 in April, defeating Che Mills by TKO. Fighting Penn was a huge opportunity for the Canadian, but now he will be unable to fight the UFC legend due to the cut suffered in training. White did not say how long MacDonald would be sidelined due to the laceration.
Penn retired from MMA in 2011, but decided to come out of his retirement to fight MacDonald, an opponent who “The Prodigy” said he felt would be a significant challenge.
UPDATE: Ariel Helwani of MMAFighting managed to obtain a picture of MacDonald after receiving stitches from MacDonad’s manager, Lex McMahon.
UFC 152 goes down Sept. 22 from the Air Canada Center in Toronto, Ontario, Canada. The event is headlined by a flyweight championship bout between Joseph Benavidez and Demetrious Johnson.
