Packers' John Crockett: Suffers shoulder injury

Crockett left Friday's preseason game against the 49ers with a shoulder injury.

Analysis:

Prior to his early exit, Crockett operated as the clear No. 3 running back, taking 13 carries for 46 yards while playing ahead of Brandon Burks and Brandon Ross. The 2015 undrafted free agent should still have a spot on the team, but if he isn't ready for Week 1, the Packers will likely retain Burks or Ross on the final roster.
