Former TUF(The Ultimate Fighter) winner Nate Diaz has signed a four fight contract, this according to Cesar Gracie who informed MMAJunkie yesterday. Diaz is scheduled to face Marcus Davis at UFC 118 where he will continue his foray into fighting as a welterweight. Previously Diaz was used to doing a hard cut to 155 but now seems to be enjoying the welterweight division with his last win coming over Rory Markham at UFC 111.

UFC 118 will be the promotions first event in Boston, and UFC president Dana White is pulling out all the stops with a very solid card. The main even bout will feature a rematch between current lightweight champion Frankie Edgar and former champion BJ Penn, as well as a co-main event bout between Randy Couture and boxing star James Toney.

Already a veteran of ten fights in the UFC, Nate Diaz has recently agreed to terms that will see his tenure with the promotion extended for another four bouts.

News of the contract extension comes courtesy of Cesar Gracie, Diaz’ manager and trainer, who recently relayed the news to MMAJunkie.com.

Diaz recently moved up to the welterweight division after spending the bulk of his career at lightweight. He is curently scheduled to face off with Marcus “The Irish Hand Grenade” Davis at UFC 118 in Boston on August 28.

Diaz will be looking to notch his second consecutive victory in the welterweight division after recently stopping Rory Markham via first round TKO, while Davis is also looking to make in two in a row after stopping Jonathan Goulet with a second round TKO in his last trip to the Octagon.

Newly minted welterweight Nate Diaz will re-up with
the UFC for four more fights.

The fighter's manager, Cesar Gracie, today told MMAjunkie.com that the new contract will be finalized today.

Additionally, Diaz is signed to face Marcus Davis on the first televised
bout of Aug. 28's UFC 118 in Boston. TD Garden, the city's revered
sports arena, hosts the pay-per-view event.

Randy Couture and James Toney seem to be on different scales when it comes to their fight.

This past Saturday, Toney told MMAjunkie.com that the boxer vs. MMA fighter bout, which is scheduled to co-headline Boston's UFC 118 event on Aug. 28, will be a catchweight affair. UFC officials later confirmed the plans.

But Couture's representatives today said that they've heard no such thing, and the UFC Hall of Famer is expecting to fight at heavyweight.

New York, NY, June 24, 2010 – Spike TV will showcase two of the Boston area’s finest mixed martial arts fighters in live undercard bouts from “UFC 118: Edgar vs. Penn II” on Saturday, August 28 at 9:00pm ET/6:00pm PT. Live from the TD Garden in Boston, Joe Lauzon (“The Ultimate Fighter 5” alum) of Bridgewater, Mass. takes on Terry Etim in a lightweight battle and Milford, Mass native Jorge Rivera (“The Ultimate Fighter 4” alum) meets Alessio Sakara in a middleweight clash.

Lauzon (17-5) burst onto the mixed martial arts scene with a shocking knockout of former lightweight champ Jens Pulver at UFC 63 in September 2006. A cast member of “The Ultimate Fighter 5,” Lauzon won his first three UFC bouts before losing to fellow New Englander Kenny Florian via TKO in April 2008. After winning two of his last three fights, Lauzon needs a win in front of his hometown fans to ascend to the top reaches of the lightweight division.

Fighting out of Liverpool, England, lightweight contender Terry Etim (14-3) has won four of his last five bouts in the Octagon® and is unquestionably one of the UK’s finest prospects. But to take that step to the next level, he must get past Lauzon on August 28th. This marks the sixth time Etim has fought live on Spike TV
Veteran fighter Rivera (18-7) has won a career-best three straight UFC fights including most recently a second-round TKO over Nate Quarry (“The Ultimate Fighter 1”) in March. The 38-year-old will fulfill a life-long dream as he will step into the Octagon for the first time live in front of his partisan hometown Boston crowd.

Fighting with American Top Team in Miami, Sakara (19-7, 1 NC) switched to fighting middleweight 2 ½ years ago, and after dropping his first fight to Chris Leben at 185 lbs, he has won his last three bouts. The veteran slugger is coming off an impressive 1st round TKO over James Irvin this past March.

Other bouts on the card might air on Spike TV, to be determined by the length of the fights.
