shirts

[bbman]

Worked with a fellow ref the other day. At the pregame he made the following comments:
1. Ok girls, shirts- must all be tucked in or all left out (referring to the entire team).
2. If during the game he sees midrif, he's going to issue a yellow card.
3. At the start of match, only the 6 starters are allowed to assemble on the back line, then approach the net on whistle to shake hands.

#3 sounds correct, but I never thought of it.

Thanks in advance
