Having trouble translating from a crappy scan, but these two panels look like someone with a bit more skill than me could figure them out - so MH, I call upon your powers!
This is random spectator after a fight in a tournament. "Well, they did (say?) his (joints?) were weak."
I can pick out a few kanji in the blurry section, but not enough to figure out the meaning.
1. Possible translation:
Damn it, I thought his(opponent's) joints were weak.
I can't read the letter... I am just guessing...
Letters in bold should be correct.
Works for me. Thanks, mikkih!
I wouldn't translate 絶対 part though. It's probably wrong. 徹底的にねじ伏せ should be good enough to carry on your translation.
