What is the main event at UFC 73?

Is it Tito/Rashad or Silva/Marquardt?

Is that definite? With two titles on the line, you would think that they would have precedence??

I think it will be Silva, then Tito/Rashad, then Sherk....from top to bottom that is...

I think it's Tito/Rashad.

It seems like, in the past anyway, that the heavier weight class title fight...is the main event. They may change things, but who knows.

Let's say there co-main events.

That's the way I'm looking at it at least.

Title fights should be the main event.

Silva vs Marquardt

is the last fight of the night.
