It appears the Green Bay Packers will be without a number of key starters and contributors for Sunday’s game against the Cincinnati Bengals, despite the optimism of coach Mike McCarthy. Left tackle David Bakhtiari (hamstring), safety Kentrell Brice (groin), wide receiver Randall Cobb (chest), defensive end Mike Daniels (hip), cornerback Davon House (quadricep), outside linebacker Nick Perry (hand) and inside linebacker Jake Ryan (hamstring/concussion) are all listed as doubtful after being unable to practice Wednesday and Thursday. Right tackle Bryan Bulaga (ankle) and wide receiver Jordy Nelson (quadricep) were listed as questionable after practicing in a limited capacity during the week. “I think that that group of guys that haven’t practiced yet, we’re going to give them the week to go through,” McCarthy said during his Friday news conference. “Today’s a day (that) will obviously help all the players, let alone the injured players, because it’s meetings and walk-throughs and then you have the STAA (soft-tissue activation and application) program at 1:15. “Hopefully, we’re improving and really, the practice lineup tomorrow will tell the story.” The STAA program is part of the rest-and-recovery day that is built into the Packers’ workweek. It requires the players to take part in some form of rehab, such as massage, and always takes place on Friday afternoons when games are Sunday. It has been in existence since McCarthy switched to the Wednesday, Thursday, Saturday practice format.
