Wow you're right, but it was for the first JMM fight...

"Toward the latter rounds, because I was wearing socks that were very thin, I had developed blisters on my feet making it very difficult for me to move as effectively as I had during the earlier rounds. I had to fight more flatfooted than we had trained. After the fight, when I took my boots off, my socks were worn through and they were very bloody."

Apparently against Morales 1, he said he lost because he had to have a blood test a few days before the fight and because he had to wear a pair of gloves he didn't like.

Then against JMM 3 he said he had "leg cramps" or some shit.

Manny "Excuse Man" Pacquiao seems to have an excuse for every fight he ever lost.
