Jose Aldo is not out of his UFC 189 main event title defense against Conor McGregor. But the UFC has a backup plan in place.

In a statement released late Wednesday, the UFC said if Aldo (25-1 MMA, 7-0 UFC) cannot defend his featherweight title against McGregor (17-2 MMA, 5-0 UFC) next month, McGregor still will fight for a belt. In the event of Aldo’s withdrawal, McGregor will meet two-time title challenger Chad Mendes (17-2 MMA, 8-2 UFC) for an interim belt.

The severity of Aldo’s injury, the UFC said in the statement, is not as bad as initially feared.

“In light of recent reports regarding the status of UFC featherweight champion Jose Aldo, UFC has received official medical confirmation from several doctors that Aldo did not suffer a broken rib,” the statement reads. “Following a review of the scans, it has been determined that the champion suffered a bone bruise to his rib and cartilage injury during training.

“With this news, Aldo has expressed that he has every intention of facing Conor McGregor at UFC 189.”

The UFC went on to deliver the contingency plan involving Mendes:

“While Aldo has indicated that he will compete in Las Vegas on July 11, UFC has confirmed a contingency plan. No.1 featherweight contender Chad Mendes will face McGregor for the interim UFC featherweight championship in the event Aldo cannot compete. UFC remains committed to delivering the featherweight and the welterweight championship fights at UFC 189 during UFC International Fight Week in Las Vegas.”

Aldo vs. McGregor is slated to headline the card, with a title fight between welterweight champion Robbie Lawler (25-10 MMA, 10-4 UFC) and top contender Rory MacDonald (18-2 MMA, 9-2 UFC) in the co-feature spot.

UFC 189 takes place July 11 at MGM Grand Garden Arena in Las Vegas. The main card airs on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass.

News of Aldo’s injury broke on Tuesday when it was reported the champion suffered a broken rib taking a kick in a training incident in his native Brazil – an initial prognosis that it turns out was incorrect.

Mendes is just one fight removed from his second title shot against Aldo. At UFC 179 this past October, he dropped a unanimous decision in a “Fight of the Night” winner. The only two losses of the Team Alpha Male standout’s career have come against Aldo. He was knocked out at UFC 142 in January 2012.

After that fight, Mendes went on a five-fight tear with four straight knockouts and a unanimous decision win over Nik Lentz to eventually earn his second title opportunity. After the loss this past fall, he rebounded in a big way with a first-round “Performance of the Night” TKO of fellow former title challenger Ricardo Lamas in the UFC Fight Night 63 main event in April.
