Shin Guards

[LaxRef]

The rules tell you what you can't do. For example, no where in the rules does it say that the players are allowed to wear contact lenses, but absent a rule prohibiting them they're legal.

I don't know of any specific rule prohibiting shinguards. There are rules about general items that the officials think might be dangerous in the NCAA rules, and I think NFHS has the same rules. I'd have a hard time imagining shin guards being dangerous to anyone, though.
