I get more annoyed when Brazilians use injury excuses. Nog had bad ribs against Herman. Silva had bad ribs against Sonnen. Palhares was sick against Belcher. Machida lost to Bones because he got an elbow to the head and had trouble seeing after. JDS beat Cain even with a torn ligament. Nog had a staph infection against Mir. Shogun wasn't healthy against Bones. Shogun wasn't healthy against Griffin. The list just goes on and on.
(Not saying Brazilian fighters are the only ones who make injury excuses, but it really does seem to happen a lot with them)
