Edelman stated that they weren't sure whether or not he'd need a second surgery. That was about 2 weeks ago. Apparently, they are trying to allow some time to heal properly first before making that determination.
I don't think it would affect him at all for the regular season--only mini camp and possibly TC, although foot injuries can be very tricky. This is why they were monitoring it so closely with xrays/MRIs after the 2 games when he came back.
@Mack Herron -- do you remember where you originally shared the tweet from, or whom it was? I can't even remember what thread we were discussing this in.
