Flanagan flew to Philadelphia today to get examined for a muscle hernia, according to Packers coach Mike Sherman. Flanagan sustained the injury last week in practice. He was bothered by it early in Green Bay's 32-29 loss to the Panthers and left the game.
Diggs injured the MCL in his right knee in the first half against the Panthers. The veteran linebacker suffered the same injury in his left knee in early August during a training camp practice, which sidelined him for more than a month.
Others who came away limping from the physical game against the Panthers include running back Ahman Green (quadriceps), offensive tackle Chad Clifton (sprained ankle) and safety Earl Little (hamstring). Sherman was uncertain Tuesday if those three players will be available on Sunday.
If Clifton is unable to play, the Packers likely will start the same line that they finished with against the Panthers. Adrian Klemm, who has been starting at left guard, was moved to left tackle in place of Clifton. Grey Ruegamer played left guard and Scott Wells center. Guard Will Whitticker and tackle Mark Tauscher man the right side of the line.
The Packers likely will sign a receiver, either from the practice squad or a free agent, to take Murphy's position on Sunday.
The Packers Tuesday waived tight end Ben Steele. He had re-signed with the Packers two weeks ago and played in each of the last two contests. He had spent training camp and most of last season in Green Bay as a reserve tight end.
Steele's release likely means that Bubba Franks will be available to play Sunday. Franks has been recovering from a badly bruised knee and has missed the last two games.
