Uh oh fight fans. Another UFC champ has been hospitalized just a few weeks ahead of a PPV-headlining bout, but the good news is it looks like his fight is still on.

This time its Jose Aldo, the 145 pound king. According to Brazil's Globo he had to be hospitalized for a kidney stone.

"Aldo has had renal calculi since he was 16 years old. After his fight against Zombie, he expelled a stone. Last week it happened again. He started to get a little pain, he was hospitalized, he got saline solution and expelled the stone," said his coach Andre Pederneiras.

Aldo is set to rematch Chad Mendes at UFC 179 on October 25 in Rio di Janeiro, Brazil. He's already had to post-pone the fight once. It was originally set for UFC 176 in Los Angeles. That whole card had to be cancelled when Aldo pulled out with a neck/shoulder injury.

UFC 176 was the second numbered event the UFC has been forced to cancel, following UFC 151's cancellation in 2012.

Aldo and Mendes fought previously at UFC 142 when Aldo KO'd Mendes in the last second of the first round with a knee.
