I hate this. But...
Can a player with a white jersey wear black upper body only "tights"? To me it looks like a long sleeved shirt and illegal.. To fellow officials who have been allowing it, they are apparently considering it "tights", though only covering the upper body. If considered tights, this falls under 3-5-3, and black under white would be legal. If considered an undershirt, then 3-4-6 applies and black under white would be illegal.
Any further confirmation by rule one way or another on this?
