Well...if we're talking about the fight in August of 1973, Munson may have been dumped on his head, but I believe Fisk was the only one that ended up bleeding.
In all fairness, I'm a big Munson fan and never really cared for Fisk, or I should say the media version of Fisk. This all changed when I had the pleasure of meeting him in 2008 at the Hall of Fame. One of the nicest players I've ever met.
