UFC 202 is finally here, and on Saturday night UFC fans will get the Conor McGregor vs. Nate Diaz fight they have long awaited. Ever since Diaz shocked the UFC's Golden Child at UFC 196 in March, this is what we've expected: a bloodthirsty rematch.

At Friday's weigh-ins, as one has come to expect from these two, things got testy. Very testy. The fighters were separated by both UFC President Dana White and police.

As they were separated, McGregor took the microphone and sent a profanity-laced string Diaz's way. "You should've killed me when you had the chance!" McGregor shouted at him.

On Wednesday, at the pre-fight media conference, Diaz stormed out. The fighters' camps screamed at each other and threw objects such as water bottles. Yep, they threw water bottles. The tension is real between these two camps. In fact, Fox Sports is reporting that someone was injured during the fight, and lawsuits are likely being filed as a result.

"The word is in this thing somebody was injured so there's going to be a lawsuit," White said. "Who knows how it's all going to play out. Somebody's filing a lawsuit. The wheels are already in motion on it." White predicted "massive fines" and "suspensions" for the two fighters.

McGregor and Diaz were expected to have their rematch at UFC 200 July 9, but McGregor was unhappy with how the UFC handled media commitments, leading him to "retire." He later, of course, un-retired.

McGregor, undeterred by his submission loss to Diaz in their first matchup, has predicted he will knock Diaz out in the second round of the rematch.

UFC 202 will get underway at 10 p.m. Saturday, but as we've come to find with these events, the main event probably won't begin until after midnight ET.
