Caol Uno confirmed his UFC comeback in a blog post on Monday.
"My participation at UFC 99 in Germany is now official," Uno wrote. "I am excited as well as worried about my fight. I feel that I'm a challenger and also have some unfinished business in the Octagon. I have mixed feelings now. I will train hard and show all I have in my fight. Thank you for supporting me."
Uno will take on Spencer Fisher at UFC 99 "The Comeback" on June 13 in Cologne, Germany.
