Duplicate uniform numbers

[blueump]

The reference you are looking for is 1-4-3

Penalty: Failure by a player to wear proper equipment after being so ordered by the umpire, shall result in ejection.

With that stated, since this is kids, and its not the player's fault for having the same number, I'd probably call it this way: If two players had the same number, one would need to change uniforms or not play. As long as he stays on the bench, I don't have a problem. He tries to enter the game, then we have the ejection. But most coaches carry a spare uniform in case blood soaks one or something like that. The spare uniform should work.
