As previously reported by MMAFighting.com, the Slidell native Clementi (36-16-1) will be making his Bellator debut in front of his hometown fans for the promotion's season three stop at New Orleans, La. at the Mahalia Jackson Theater.
Vanier (9-3) entered Bellator in April and extended his win streak to seven with a TKO victory over Joe Duarte to advance to the semifinals. But Toby Imada's submission prowess proved to much and Vanier was ousted from the tournament by way of a second-round armbar.
Also announced for Bellator 28 is a featherweight bout between season two tournament semifinalist Georgi Karakhanyan (13-2-1) and Chas Skelly (7-0) for an opportunity to compete in the season four featherweight tournament. Karakhanyan won his quarterfinal fight with a beautiful knee knockout, but fell short in the next round to eventual winner Joe Warren.
Bellator 28 will be headlined by two of its upcoming third season's semifinal bouts.
