Five more bouts have been announced for UFC 100, scheduled for July 11 at the Mandalay Bay Events Center in Las Vegas.

Yoshihiro Akiyama will make his debut in the Octagon against Alan Belcher in a middleweight matchup. A veteran of K-1 and Dream, Akiyama is seen as a a potential superstar in the South Korean market that Zuffa is beginning to target. Belcher, however, is a quality opponent, having won four of his last five in the UFC.

Light heavyweight prospect Jon Jones will also return to action against Jake O'Brien. Jones has made a name for himself as a talented wrestler who will throw a variety of strikes on the feet. O’Brien has the less interesting style but did use his wrestling to stifle Heath Herring in a January 2007 heavyweight bout.

In other bouts, Dong Hyun Kim, whose loss to Karo Parisyan was overturned recently and is now a no decision, will face Jonathan Goulet; CB Dollaway will take on Tom Lawlor; and Matt Grice will meet Shannon Gugerty.
