UFC bantamweight Renan Barao has won thirty straight tilts since stumbling in his professional debut including dominant showings against some of the sport’s best but, as the MMA world learned this weekend, he’s still a mortal man. Though not officially announced, it appears Barao suffered an undisclosed foot injury while training for a June 15 defense of his interim belt against Eddie Wineland and has been forced to withdraw as a result.

Brazilian outlet TATAME was first to report the matter, while MMAJunkie was told Barao would “probably” be unavailable for UFC 161 by one of the organization’s representatives but was undergoing additional testing on Monday before any additional moves were made.

The 30-1 Barao has notched seven wins under the Zuffa banner including success in the Octagon against Scott Jorgensen, Brad Pickett, Michael McDonald, and Urijah Faber.

It is unknown if the UFC will find a replacement in the rumble or re-schedule it for a future date. If pulled from the card, UFC 161 is still set to feature bouts between Tyron Woodley-Jake Shields, Pat Barry-Shawn Jorgan, Mauricio Rua-Antonio Rogerio Nogueira, and Dan Henderson-Rashad Evans.
