1. 1

   

   Sokoudjou vs. Nogueira

   Rameau Thierry Sokoudjou | KO/TKO | RD 1

   2007 | Pride 33

2. 2

   

   Serra vs. St-Pierre I

   Matt Serra | KO/TKO | Round 1

   2007 | UFC 69

3. 3

   

   Griffin vs. Rua I

   Forrest Griffin | Submission | Round 3

   2007 | UFC 76

   Rua was considered one of the top LHW's in the world when he came over to the UFC. Then he got sub'd by Forrest Griffin. No one saw this coming.
   

4. 4

   

   Gonzaga vs. Filipović

   Gabriel Gonzaga | KO/TKO | Round 1

   2007 | UFC 70

   I was thinking Cro Cop would knock Gonzaga out with a big headkick. Man, was I wrong.
   

5. 5

   

   Randleman vs. Filipović I

   Kevin Randleman | KO/TKO | Round 1

   2004 | Pride Total Elimination 2004

   Not only did CC lose, he got ko'd. Brutally.
   

6. 6

   

   Lauzon vs. Pulver

   Joe Lauzon | KO/TKO | Round 1

   2006 | UFC 63

   This was a pretty nasty KO from J-Lau. Made me a fan, and I'm sure it made the next season of TUF awkward, with Pulver as a coach, and Lauzon as fighter.
   

7. 7

   

   Emelianenko vs. Werdum

   Fabrício Werdum | Submission | Round 1

   2010 | Strikeforce

8. 8

   

   Penn vs. Edgar II

   Frankie Edgar | Decision

   2010 | UFC 118

   Personally, I saw this as a bigger upset than their first fight, because the first decision was terrible.
   

9. 9

   

   Chonan vs. Silva

   Ryo Chonan | Submission | Round 3

   2004 | Pride Shockwave 2004

   This one has probably gotten worse with time.
   

10. 10

    

    dos Santos vs. Werdum

    Junior dos Santos | KO/TKO | Round 1

    2008 | UFC 90

    They fed Werdum an inexperienced opponent with a submission loss on his record to a no name in order to build Werdum back up. Dos Santos had other ideas, and knocked him out quick.
