The Facts: Nelson, Jared Cook and Ty Montgomery will open Packers training camp on the Physically Unable To Perform list.

Diehards Line:All three can be activated at any time during camp. If/when that happens, they can resume practicing and are not eligible for the regular-season PUP. Nelson, coming off a torn ACL suffered last August, Cook, who had foot surgery in May, and Montgomery, who underwent ankle surgery shortly after the regular season, are all expected back in plenty of time to play Week 1.
