For the second time in eight months, a last-minute injury has obstructed Conor McGregor’s shot at a title.
Less than a year ago, it was Jose Aldo who was forced to pull out of his featherweight title defense due to a rib injury. This time around, it was Rafael dos Anjos who had to bow out of defending his lightweight title after breaking his foot. Now, McGregor will make his welterweight debut -- no title on the line -- against late substitute Nate Diaz in the UFC 196 main event on Saturday at the MGM Grand Garden Arena in Las Vegas.
