Former UFC bantamweight champion Dominick Cruz returned to the Octagon this past year for the first time in over 700 days.

Now, months removed from that win over Takeya Mizugaki that placed “The Dominator” in a position to challenge for the belt he never lost, another knee injury has struck.

Cruz underwent two surgeries to repair his knee previously. This time, he’ll need to have his other ACL replaced.

The UFC stripped Cruz of his title – he had been the only person to wear it in the promotion after they absorbed the WEC with Cruz as champion – after a groin injury knocked him out of a planned title defense with then-interim champ Renan Barao.

Reigning titleholder T.J. Dillashaw was expected to defend his belt vs. Cruz in 2015.

Cruz made the announcement via his Facebook page with the following post:

It is with great sadness to report I have experienced another ACL injury. This time it’s in the right knee, opposite side of my first and second ACL injuries.

Leading up to my last fight in September and after, I have practiced a very careful and methodical training and diet regime to keep my body healthy. Unfortunately, this is beyond my understanding and control.

I don’t have a timetable for my return but trust and know I will pour my heart and soul into returning to the Octagon.

I want to thank the UFC, my fans and my sponsors ahead of time for your support and prayers. I appreciate you more than you could understand.

I don’t have any other facts to share right now. I, along with my camp, respectfully request privacy at this difficult time. Thank You.
