You should be ok. Suck it up and go. I had knee surgery two days before season opener last year, as well as recovering fromcutting two fingers off, and I did not miss a day last year.
Actually, do what you feel is best for you. Im a little different than normal, im use to surgery. I had three knee sugeries in college athletics as well as ankle surgery. I had to redshirt mySr. year, which was good because I was healthy formy last season. Thank goodness I started as a true freshmen.
