UFC Fight Night 20, featuring a lightweight main event between fellow former TUF 5 housemates Gray "The Bully" Maynard and Nate Diaz, pulled in an average of 1.7 million viewers and a 1.2 share for Monday's Spike TV broadcast, according to the network.

The numbers are worth looking at because the event was held on a Monday, which is clearly not standard protocol for a UFC show. WWE's "Monday Night Raw" has traditionally owned the Monday night ratings slot, and, apparently it still does despite the the powerhouse promotion's latest efforts.

That's right, WWE dominated the numbers by hauling in an average of 5.45 million viewers. For those keeping score at home, that's more than three times that of the UFC.

Of course, it didn't hurt that WWE president Vince McMahon had booked former boxing heavyweight champion "Iron" Mike Tyson as the quest host. For some reason, people still can't seem to ever get enough of the Bronx bomber.

UFC President Dana White expressed before the fight that going head-to-head competing for ratings with the WWE on Monday nights is not something that will become a regular thing.

Looking at these numbers, who could blame him?

Here's a snip:

"I love Vince. He's an animal isn't he? I mean, we're not trying to go against him. That night is the night Spike wanted the fight. Spike wanted the fight that night. They got some show airing, so that's the night that they called for. Vince goes into war mode man. He's calling up Tyson, he's bringing this guy back and the Rock might come back. I love it. He's a fucking animal. To be honest, you've never heard me say, "we're going to kick the shit out of them. Vince is going down." I think that we're two totally different, you know, wrestling is completely different than the UFC and mixed martial arts. I respect Vince McMahon. I like this guy. I've had breakfast with him, this and that, but he is a fucking animal man. I'm not trying to beat him on Monday night. I don't think we would beat him. Those guys pull killer ratings. It's been like the highest rated show on television forever. We're just putting on a fight on Monday night because Spike wants us to. Now if he was in the MMA business, that would be a whole different ballgame."
