The five-time All-Pro — and the only tackle in the NFL to earn either first- or second-team recognition in each of the last five seasons — was never likely to be ready for the season opener against the New Orleans Saints.
However, he would have needed to pass his physical to be on the 53, but a player cannot go from the PUP list to the roster to IR in one cycle for the same injury.

The Packers had a three-player competition this summer for the two starting guard spots between Lucas Patrick, fourth-round pick Royce Newman and Jon Runyan Jr.
If Newman wins one of the starting jobs as expected, likely at right guard, the Packers will open with a pair of rookies on their offensive line.
The Packers had one of the best offensive lines in the NFL last season until Bakhtiari went down the week of the regular-season finale.
