With the window of opportunity for post-season play rapidly closing, the Green Bay Packers are dealing with a growing number of injuries. Eight players missed Wednesday’s practice. Coach Mike McCarthy says left tackle David Bakhtiari is improving, but kick returner and wide receiver Trevor Davis is out for the Arizona game. Others who didn’t take the field Wednesday are cornerback Bashaud Breeland, safety Kentrel Brice, running back Tra Carson, defensive end Mike Daniels, tight end Jimmy Graham and safety Raven Greene.
