blood spots on jersey -- what to do?

[Nick_O]

The NF and NCAA make reference to excessive or uniform-saturated blood, respectively, but what do we do with a player whose uniform has a spot or a few spots of blood on it? I searched high and low through the books, but could not find anything specific.

I went with "the uniform was treated by a trainer, so it's OK for the player to continue to play with the uniform that has (now-treated) blood spots on it," but I was not 100% sure that this was correct.

Thoughts or rulings to confirm or refute my ruling? Thanks!
