Blood, blood, ref, she's bleeding!

I don't want to start another tongue stud or held ball thread, but I always thought the jersey needed to be "saturated" with blood.

I do make players leave for excessive amount of blood and I'm all for ruling on the side of safety, but how do they get past a rule like this in the NFL? A player like Jon Ritchie of the Raiders has blood coming out of his forehead and no one ever says a word about the possible ramifications of letting him play.
