Green Bay Packers offensive tackle David Bakhtiari underwent a third surgery on his knee, and it's unclear if he will return in time for the start of the regular season on Sept. 11, via Rob Demovsky of ESPN.
Packers general manager Brian Gutekunst provided an update on Wednesday:
"We're not going to put a timetable on it, but what I will is Dave had a very significant injury—much more than just an ACL way back when it occurred. I thought he busted his tail to get back last season. As we went through that last game versus Detroit, I think when he came out of that he wasn't particularly happy with how it responded.
