Buentello has notable victories against David “Tank” Abbott, Gary Goodridge, Justin Eilers, Mike Kyle, and Kirill “Baby Fedor” Sidelnikov.

In other title fights on the card, former WEC champion Jason Lambert faces Brazilian Jiu-Jitsu champion Allan Goes for the vacant PWP light heavyweight title belt, while former UFC title challenger Thales Leites fights UFC and Strikeforce veteran Falaniko Vitale for the middleweight crown.

Former UFC lightweight champion Jens “L’il Evil” Pulver returns to action in his first fight since leaving the WEC to face Diego Garijo.

Also fighting on “War on the Mainland” are Brazilian middleweight Gustavo “Ximu” Machado vs. Rick Reeves, Mexican welterweight Jorge Ortiz vs. UFC veteran Terry Martin, and California lightweights Joao Silva vs. Erin Beach.

“The depth of our field is unmatched. We not only wanted to make sure that we had three really good fights like we do, but to insure that all of the fights on this show would feature high quality fighters, as well as competitive, entertaining matches,” said PWP CEO Brian Manna.

The event will be carried live on pay-per-view.
