UFC PR Vice President Dave Sholler revealed the news on Twitter.

Well that was short lived. Just three days ago, it was reported that Augusto “Tanquinho” Mendes would take on Charles Rosa on a week’s notice at UFC Fight Night 81. However, reportedly just moments after he signed the contract, Mendes suffered a rib injury. Undefeated prospect Kyle Bochniak has signed on to fight Rosa on three days’ notice.

Kyle Bochniak just fought last Friday as a part of the CES MMA promotion. He only needed four minutes to choke out his opponent, so he is jumping right back in the cage against Charles Rosa. The victory pushed his professional record to 6-0, with two knockouts, two submissions, and two decisions. The Boston, Massachusetts, product also has two amateur knockouts and two amateur submissions to his name. Bochniak is trained under Carlson Gracie.

Augusto Mendes has a laundry list of jiu-jitsu accolades that can be seen here. The list includes a world championship victory in 2013. A year later, “Tanquinho” transitioned to mixed martial arts and has won all five of his fights (four via submission, one via knockout). Most recently, the Brazilian has fought under the Legacy FC banner, with his last appearance coming in July of last year. Following the injury, Mendes was guaranteed a future fight in the UFC.

Charles Rosa made his UFC debut on short notice against Denis Siver in October of 2014. The Boston native ended up losing the bout, but he was awarded “Fight of the Night”. Rosa bounced back with a d’arce choke submission with just 17 seconds remaining in his next fight, then he received a tough step up in competition. One of the most promising prospects in the UFC, Yair Rodriguez, met Charles Rosa in the octagon in Rosa’s latest appearance. Rodriguez battered the grappler with his acrobatic striking for three rounds, earning the pair a “Fight of the Night” bonus.

UFC Fight Night 81 is headlined by the bantamweight championship fight between TJ Dillashaw and Dominick Cruz. Also, former UFC champion Anthony Pettis will fight former Bellator champion Eddie Alvarez in the co-main event of the Boston, Massachusetts, event.
