Sixteen lightweight mixed martial artists head to Vegas for their chance at a UFC glory and a six-figure contract. And for the first time on the series, coaches BJ Penn and Jens Pulver will fight each other on the season finale.

BJ Penn has a surprise for Jens Pulver. Choice words cause an eruption at The Ultimate Fighter House. And another lightweight’s dream of a UFC contract is crushed in the Octagon.

Team Pulver is 2-0 against Team Penn and BJ is not happy. Gabe continues to struggle with his weight making him a possible target for the next fight. And Team Pulver gets a surprise guest coach.

One fighter tries to take an easy path through the competition while another fighter disappoints his coach during crunch time. Team Pulver gets a surprise visitor and two more fighters step onto the battlefield.

Team Pulver has racked up four wins in a row against Team Penn. Still struggling with his weight, Gabe Ruediger is the likely target for Team Pulver’s winning machine.

It’s two fights in one show. It’s Joe Lauzon vs. Brian Geraghty, followed by Rob Emerson vs. Corey Hill. Who will move on to the next round and gets a shot at the ultimate prize?

After five humiliating losses, BJ shakes things up and kicks one of his fighters off his team and the next two fights marks the end of the preliminary round of the competition.

Tensions at The Ultimate Fighter house reach an all time high and a fight breaks out. The quarterfinal match ups are announced. Who will be the first lightweight to make it into the semi-final round?

Guest Coach Randy “The Natural” Couture pays a visit to Team Penn to offer his expertise and to support one of his protégés’ Gray Maynard as he prepares to enter the quarterfinals against Brandon Melendez.

It’s the last two quarterfinal match ups. Two fighters from Team Pulver go head to head in the third quarterfinal fight but only one will advance to the semi-finals. And Manny gets a visitor as he prepares for the last quarterfinal bout.

Manny Gamburyan’s cousin and UFC veteran Karo Parisyan almost gets into a fist fight with Nate Diaz and the first semi-final fight takes place with the winner moving one step closer to becoming the next Ultimate Fighter.

It’s mayhem at The Ultimate Fighter® House as the fighters go stir crazy. And Gray Maynard faces Nate Diaz in the last semi-final match to determine who will move on to fight Manny Gamburyan in the live finale on June 23rd at the Palms Hotel.

UFC returns to The Pearl at The Palms for The Ultimate Fighter 5 Finale. The main event will feature Jens “Lil’ Evil” Pulver vs. BJ “The Prodigy” Penn while Nate Diaz faces Manny Gamburyan for the title of Ultimate Fighter.
