N-F-L Network says Green Bay Packers’ rookie Montravious Adams suffered a stress fracture in one of his feet, and it’s not known how long he’ll be out. The third round defensive lineman from Auburn apparently suffered the injury during last Friday’s practice at Training Camp since he did not work out either Saturday or Monday. Coach Mike McCarthy says it’s too early for concern — but the injury is still unfortunate because of the practices that a promising rookie like Adams will miss. Veteran lineman Ricky Jean Francois says it appears that Adams had adjusted to making pro style moves on the line. Second year defensive lineman Kenny Clark says Adams is explosive off the line and his upfield moves appeared excellent.
