Jennings close to return from concussion

The good news for the Green Bay Packers in their 35-10 preseason loss to Cleveland on Thursday night was that the team didn’t suffer any significant injuries. But coach Mike McCarthy still had some significant updates to the team’s lengthy injury list when he addressed reporters Friday afternoon.

Two-time Pro Bowl wide receiver Greg Jennings, who has been sidelined since suffering a concussion in the team’s Aug. 3 Family Night scrimmage, could practice Sunday after following the league’s protocol for returning to the field following a head injury.

Linebacker Desmond Bishop, the Packers’ leading tackler in 2011 who suffered a severe hamstring injury in the team’s preseason opener, had surgery Friday morning. Bishop could miss the season with the injury, and McCarthy didn’t offer any further updates on his condition other than to say he is “doing well” and that the team has not yet decided whether to place him on injured reserve.

Jennings’ return will be welcomed by a Packers offense that has struggled in its first two preseason games. With him and several other starters missing, the first-string unit that shone so bright in the team’s 15-1 2011 regular season has been plagued by mistakes and fumbles. In six drives over two games, the Packers’ starters have produced seven points and three turnovers.
