Antonio Rogerio Nogueira injured, out of UFC 161 fight with ‘Shogun' Rua

Not long after the original UFC 161 main event of Renan Barao vs. Eddie Wineland was scratched due to a Barao injury, another major blow has been dealt to the Ultimate Fighting Championship's (UFC) next pay-per-view (PPV) event.

According to a report from Brazilian news outlet SporTV Globo, Antonio Rogerio Nogueira suffered a back injury in training and will be unable to compete against Mauricio Rua in the co-main event of the June 15, 2013 event.

John Morgan of MMA Junkie confirmed the news with UFC officials, who stated they are actively seeking a replacement to meet "Shogun" at the organization's second event on Canadian soil in 2013.

The news comes at an unfortunate time for "Minotouro," as he was celebrating his 37th birthday alongside twin brother Antonio Rodrigo Nogueira on Sunday (June 2, 2013).

UFC 161: "Evans vs. Henderson" takes place June 15, 2013 from the MTS Centre in Winnipeg, Manitoba, Canada and features a main event between light heavyweight contenders Rashad Evans and Dan Henderson.
