blood on sock

[whitehat]

Another philisophical dilemna is if this player (lets say starting QB) at a critical time in the game should be told to get out right then and clean it up. Please don't repeat the rule... I know what the rule is...

Lets says the QB has played with that blood on his knee for a few plays (not that this matters, but verily likely scenario), we just now spot it, are we going to tell him right now, on 4th and goal with a tie score and 20 seconds to go in the game to go sit out a play and clean off his knee?

My personal philosphy makes me very reluctant to do that.

What think ye my fellow zebras, especially R's?
