Jose Aldo injured; UFC 189 bout with Conor McGregor in jeopardy

Jose Aldo has suffered an injury in training, which has left next month's UFC title defense in jeopardy.

The first and only UFC featherweight champion, who is scheduled to fight Conor McGregor in the highly-anticipated main event of UFC 189 in Las Vegas on July 11, fractured his rib in training and will potentially require three-to-four weeks of treatment to get completely healed. As of right now, though, Aldo has not decided whether he will have to pull out of the fight.

The news was first reported by Combate, which MMAFighting.com later confirmed with sources close to the situation. MMAFighting.com reached out to Aldo's manager and Nova Uniao head coach Andre Pederneiras for a comment on the situation, however, he did not respond.

Aldo (25-1) last defended the 145-pound title against Chad Mendes in October. He was initially slated to defend the belt against Mendes in August, but he pulled out of UFC 176 with a shoulder and spine injury. McGregor (17-2) earned the title shot after UFC wins over Marcus Brimage, Max Holloway, Diego Brandao, Dustin Poirier and Dennis Siver.

Should Aldo pull out of the fight, it would be a devastating blow to all involved, as the UFC has invested millions of dollars into promoting the fight, which is the centerpiece of next month's International Fight Week in Las Vegas.
