There has been endless debate for nearly two weeks about whether UFC featherweight champion Jose Aldo actually fractured a rib during training or whether he had a deep bruise, as the UFC has said. The injury, whatever it was, forced Aldo on Tuesday to withdraw from a planned title defense on July 11 against Conor McGregor in the main event of UFC 189 at the MGM Grand Garden. Aldo has come under attack for pulling out of a fight for the fifth time in his brief UFC career.
