Harvison, who was bounced out of season 13 courtesy of a Ramsey Nijem -- the show's eventual runner up -- rear naked choke in the quarterfinals. He rebounded at TUF 13 Finale, scoring a split decision over Justin Edwards after three rounds of action.
"Battle on the Bayou" will feature a pair of welterweight wrestlers hitting the mat in the main event, as Jake Shields will return to action to take on hard-hitting grappler extraordinaire Jake Ellenberger. Also booked for "The Big Easy" is a middleweight showdown that will showcase the triumphant return of Alan Belcher, who was nearly blinded in an unfortunate training accident, when he takes on veteran Jason MacDonald.
