Well, I totally see where you're coming from. I would feel the same way. Because really, it's not like he was hit in the nose on pupose the first time...so to say that he'll play and "just not get hit in the nose" doesn't really make sense. lol! Accidents happen. I would be paranoid about it too.
That being said, IF something were to happen and IF he had to have surgery, it would all be done and healed before the wedding for sure. AND you can always let him know that after you guys have to fork out $$ for the new nose, no way in hell is he ever doing anything again to jack it up! That's what I'd say anyway! Lol! SO yeah, if he wants to play this week, fine. But IF he has to have surgery, no more football until after the wedding....and maybe agree to no heavy hitting contact sport the month before the wedding anyway....I bruise like crazy at the drop of a hat and I definitely did everything I could to NOT bruise before my wedding. It's only sensible that he could be cautious too...nobody want a broken arm on their wedding day or anything like that! :-)
