Nobody wants Jose Aldo to beat Conor McGregor more than Joe Riggs, not even Jose Aldo.
Riggs, who last appeared in the octagon with a victory over Ron Stallings in September, is so confident of an Aldo win that he has made an outrageous promise if McGregor comes out on top.
While some fight fans will be putting a few quid on the Brazilian champion to be victorious at odds of 5/4, the UFC 49 veteran has much more on the line.
"It makes me sick," Riggs told the Fight Network. "The fact that the guy who's considered the pound-for-pound best fighter on the planet and he's the underdog against this guy who's fucking nothing.
"No way, if he [McGregor] beats Aldo, I'll cut my own dick off and throw it away."
