Aldo does have a rib injury, but just not a fracture.
Aldo has a bone bruise and cartilage damage in his ribs, and is scheduled to fight Conor McGregor in the main event of UFC 189 on July 11, 2015.
However, the status of Aldo’s injury is tenuous, and it’s possible he would not be cleared for the event.
If Aldo does get cut from the fight, UFC has decided on a backup.
UFC 189 would headline with McGregor vs. Chad Mendes in a match that would be a five round fight for the interim featherweight title.
