Yeah, it was an accident but he was disqualified because he put weight on that hand and he would have fallen if he hadn't done it. I have the whole thing on videotape somewhere. I love this show.
5 stars for Ninja Warrior even though Tokyo Broadcasting System took the video off youtube. -5 imaginary stars if it used the awful British dub.
At any rate, it saddens me greatly that G4 seems to be fucking this show up badly lately. (but at least they don't dub the awesome Japanese announcer with some lame unfunny bullshit).
