FanHouse Nate Diaz

Nine-time UFC competitor Nate Quarry was the top earner with $60,000 at last Wednesday's UFC Fight Night 19 in Oklahoma City, Okla, according to the disclosed salaries Oklahoma athletic commission provided Monday to FanHouse.

Next were main event winner Nate Diaz and former WEC welterweight champion Carlos Condit, who both pocketed $48,000 ($24,000 to show plus another $24,000 for the win).

Former Ultimate Fighter winner Nate Diaz snapped a two-fight losing streak inside the Octagon Wednesday at UFC Fight Night 19, beating Melvin Guillard with a second-round guillotine choke in the main event of a solid night of MMA.

Guillard dropped Diaz with a brutal right hand just seconds into the fight, but he didn't want to go to the ground with Diaz, a Brazilian jiu jitsu black belt, and so he allowed Diaz to recover and stand back up.

Nate Diaz was the only fighter to miss the mark on his first weigh-in attempt but had extra time to cut the weight and make official his lightweight bout against Melvin Guillard for Wednesday's UFC Fight Night 19 in Oklahoma City.

Diaz initially stepped off the scales at 156.5 pounds, which is half-a-pound over the one-pound allowance, but his second try allowed him time to cut down to 156. Guillard weighed in without needing any allowance at 155 pounds.

The word out of Diaz's camp coming into the weigh-ins was that Diaz was having difficulty getting down to lightweight and hinted at a move to welterweight after this fight.

All 22 fighters will step on the scales Tuesday afternoon at the Cox Convention Center in Oklahoma City for the UFC Fight Night: Diaz vs. Guillard weigh-in, and if you can't be there in Oklahoma, you can watch it right here at FanHouse.

The big question is whether Nate Diaz, who fights Melvin Guillard in the main event, will have any trouble making the lightweight limit of 155 pounds. Diaz's camp has indicated that he might have a hard time making weight.

Will Diaz make weight? Will everyone else? Find out by watching the weigh-in video below, starting at 5 PM ET on Tuesday.

Melvin Guillard in recent years has put his fight career in jeopardy with a positive cocaine test, a controlled substance charge and a probation violation, which have led to jail time and an eight-month suspension, but it wasn't until the five-month stint in rehab late last year that handed him his wake-up call.

"The turning point for me was when I had to sit in a rehab – which to me which was jail – I had to sit there for six months," Guillard said Monday in a conference call. "Those six months gave me time to miss my family. I missed my wife. I missed the sport.

The UFC has added one more bout to UFC Fight Night 19, the UFC debut of former Sportfight champion Mike Pierce against former WEC welterweight title contender Brock Larson (pictured, right).

The event, co-headlined by Nate Diaz vs. Melvin Guillard and Gray Maynard vs. Roger Huerta, emanates from the Cox Convention Center in Oklahoma City on Sept. 16 and will air as the lead-in on Spike TV to the season premiere of The Ultimate Fighter: Heavyweights.

Ten bouts have now been official to finalize the UFC Fight Night 19 card scheduled for Sept. 16 at the Cox Convention Center in Oklahoma City.

In the evening's headliner, The Ultimate Fighter 5 winner Nate Diaz will look to avoid three straight losses in a lightweight showdown against season two's Melvin Guillard.

In a battle of former Ultimate Fighter winners, Joe Stevenson ended a two-fight losing streak by defeating Nate Diaz by unanimous decision Saturday night at the Ultimate Fighter Finale.

The first two rounds were full of action on the canvas, with Stevenson clearly showing that he has improved his jiu jitsu skills by getting the better of Diaz -- a Gracie jiu jitsu brown belt -- on the ground.

Two up-and-comers will get six-figure UFC contracts, and the No. 1 UFC lightweight contender may be determined, at Saturday night's Ultimate Fighter Finale. We've got the full preview and predictions below.
