The event takes place August 17 from the TD Garden in Boston. Previously, Overeem had said on Twitter that he would be fighting at UFC 164, which is set for later in August.
Overeem (36-12) lost his last match, suffering a knockout defeat at the hands of Antonio Silva. “Bigfoot” is also the only fighter to defeat Browne (14-1-1), having stopped him last year.
After his loss to Silva, Overeem was scheduled to face Junior dos Santos. A training injury, however, knocked him out of the bout.
