Newly pierced earrings and sports?

Question

I play soccer, and lacrosse. For the two sports there are rules stating that earrings cant be worn during the game. Would it be okay if I get my ears pierced one week before the season starts?

For example: If I had a practice or game and I took out my earrings right before it. After the practice or game was over could I just put the earring back in? Or would the hole already be closed?

My questions

1.Would it be okay if I get my ears pierced one week before the season starts?

2.After the practice or game was over could I just put the earring back in? ( after one week)

3. If I do take my earrings out a week after I get them pierced how quick will the holes start to close?
