I couldn't find any other threads about this but I swear BJ Penn looked like he was crying when walking to the octagon. His eyes were red and puffy. Am I imagining this? No one else that I asked at the fight seemed to notice.
I saw this too, I seriously thought he was crying on his way to the cage. I wonder if he was already planning on retiring and figured it would be his last walk out. 
I noticed it also.
He was, and it got me even more pumped! I love when fighters show their emotion like that. 
Yeah, some of my friends noticed it too.
a lot of emotions running through his body before the fight.
