UFC 85 Main Event is now...

Matt Hughes vs Thiago Alves

From Matt's site (http://www.matt-hughes.com/):

"June 7th, in England, I fight Thiago Alves. The fight is confirmed, it will be the main event for the card. Dana just called me with the news. Chuck got hurt and couldn’t fight, so he needed a replacement and called me and I said yes. More news as I get it. No matter what happens in this fight, I’ve got Serra next. -matt"

It's a pretty good match-up imo, Alves's win against Karo Parisyan has really propelled him up the contender ladder and Hughes is the next logical step.

Good fight.
