We definitely are aware of his history, and that will factor in how we move forward.Shields was slow to get up after he tackled Jaguars running back T.J. Yeldon in the fourth quarter of Sundays 27-23 win, but he was able to walk off the field under his own power.Last season, Shields missed the final three games of the regular season as well as the wild-card playoff game at Washington after his head slammed onto the Lambeau Field turf in the teams Dec. 13 game against the Dallas Cowboys.If Shields is unavailable for next Sunday nights game, the Packers will turn to a trio of young cornerbacks in second-year pros Damarious Randall, Quinten Rollins and LaDarius Gunter.While Randall played well as the other starter against the Jaguars, Rollins was benched midway through the game in favor of Gunter, who also struggled.
