Packers' John Crockett: Likely out for Week 1

Crockett (shoulder) is not expected to be ready for Week 1, ESPN.com reports.

Expected to open the season as Green Bay's No. 3 running back, Crockett may instead land on injured reserve. Undrafted rookie Brandon Burks is the obvious roster replacement, though he probably can't match Crockett's expected contribution on special teams.
