Marinating chicken

So I decided to marinate some chicken breasts for supper in a vinaigrette marinade. However SO and I got invited out so we decided to leave the chicken for tomorrow. Will marinating it overnight in the fridge be too much ?

Leave it the fridge covered it will be fine.

Nope, i always marinate my stuff at night.

Typically when you marinade a chicken in a vinegar for long periods of time, it "burns" the meat. I would cook it up tonight and reheat it tomorrow or something :/

Does the "burn" make it a health risk or just not as good of a flavor?

As far as I know, from experience, it just makes it taste absolutely terrible. Not sure though really.
