With all the hype surrounding Saturday's headline showdown, there are a couple of main event fights that have gone a little under the radar.

Thursday was workout day for the Saturday's competitors, which gave the media a chance to talk to a number of the other fighters.

(Two dozen media members, UFC staff and half a dozen fighters crammed into a small locker room, an olfactory pleasure, right?)

Actually the accommodations were just fine and not too many worked up too much of a sweat, anyway.

There was the usual throng of people with cameras and recorders who flocked to Georges St. Pierre when he came in (he was the last to make his way in). But Thursday was the opportunity to see some of the other fighters on the card. In particular, there were a couple guys fighting on two other pretty important bouts at UFC 94.

Let's start with the co-main event featuring two undefeated Brazilians (only when two champions square off on the same night does a matchup of two 13-0 fighters go under the radar.)

Thiago Silva and Lyoto Machida are each looking for that one more win to put them in line for a light-heavyweight title shot. (The winner will almost certainly either fight for the belt next or have to wait one more, depending on the outcome of the upcoming Quinton Jackson-Keith Jardine fight.)

Neither one speaks English, so talking to them involves some help from a Portuguese translator, in Lyoto's case, it was his manager Ed Soares. Machida for one said he likes it better when there's a little more anticipation for one of his fights.

"It adds a little more pressure," he said. "There's still that pressure, but I would like it if it were a little more talked about."

I'm sorry to tell you Lyoto, but one reason people might not talk about you as much is because you're just a tad boring! Machida is a fighter whose style isn't exactly liked by everyone who watches his fights. He plays a strategic and defensive game that's effective but doesn't always produce exciting fights.

But Machida is a winner (obviously). And I have a feeling Saturday's will be a little more interesting. Why? Because of his opponent, Thiago Silva, who you might say is the exact opposite.

"I come to fight," said Silva, who is a very aggressive dude.

Although, you wouldn't necessarily know it from Thursday's workout. Silva did a little bit of shadowboxing but that was about it. His coaches made sure he didn't do too much -- they want to make sure he comes in as close to 205 as possible at Friday's weigh-ins (preferably 206, allowable since it's a non-title fight.) And then he expects to put the weight back on fast.

"My weight is 240 pounds," he said (translated). "And I will be bigger -- my coaches are fantastic!"

The other fight that's quite notable is between Clay Guida and Nate Diaz. If I were to put money down on UFC 94 (this is Vegas, after all) it would be for this one to be the fight of the night.

Guida has a knack for that because of his frantic style of attack, and that was on display Thursday. He had the most crazy workout I've ever seen (a nice contrast to Thiago). He started with the medicine ball, then followed with some heavy jump rope, did some pad work, sparring, takedowns (with a trainer) and even did some jiu-jitsu and ground and pound from full guard. If he needed to shed a couple pounds before tomorrow, that certainly helped.

But that's just the way he is all the time.

"Yeah, it's how I go, man. 100 per cent, 110 per cent all the time," Guida said. "My plan is to punish Nate. He's been close to breaking. We're going to break him."

Diaz wasn't there to counter that claim (wasn't scheduled to workout), but I did pass by him and his brother in the MGM Grand. As usual, he had his posse and looked like he was having a good time.

He better come really focused Saturday, because the winner of this fight will make a nice move up the lightweight ladder. Though they'll still be a ways away from Penn.

Tomorrow, it's the weigh-ins, which you can catch live on Sportsnet.ca.
