Former UFC interim heavyweight champion, Shane Carwin is returning to MMA this year when he competes for Rizin in the promotion's open weight World Grand Prix tournament. He took to Reddit to make the official announcement, and to address the rumors that he could be fighting Fedor Emelianenko.

"I made an agreement to fight Fedor," he wrote. "But, he did not agree. I have been told by several matchmakers that that fight is a unicorn, and they do not see Fedor taking it. Maybe I can just go help him train for the next one."

Even though he won't be fighting Emelianenko like we had all hoped, he is finally an official part of Rizin, despite turning down multiple offers from the promotion.

"I told Rizin no few times and they stayed with me," Carwin wrote. "Understood my values and what is important to me. Seemed to share the same values. I left the meeting wanting to be a part of Rizin. Feeling as if they wanted me."

In addition to Rizin, he says he also received offers from other major promotions, including Bellator.

"Bellator made the best offer. It just was not entirely clear that they wanted me as much as I wanted them to want me," he wrote.

Carwin will compete in the World Grand Prix tournament in Saitama, Japan, on December 29, however, no opponent has been named yet.
