There are several big names in poker who did not survive their day 1 at the main event. With the fields being so large it is very hard to survive even if you are a very skilled player. There are a bunch of donks of whom some will suck out and take out a big player.
If you want to see some other big names that are out just scroll down.
(From memory)
Mike “The Mouth” Matasow(sp?)
Doyle Brunson
Jennifer Tilly
Liz Lieu
Greg Raymer
Eric Sidel
Jennifer Harman
Sammy Farha
Jacobs (cant remember his first name)
Negreanu gone. Gus Hansen is still my favorite, though.
