Packers running back Ahman Green is out for the season with a torn thigh tendon, the latest in a string of severe injuries to befall Green Bay. Coach Mike Sherman said Monday that Green will undergo surgery this week to repair his right thigh tendon, which was torn in the fourth quarter of the Packers' 23-20 loss at Minnesota on Sunday. Sherman also said wide receiver Robert Ferguson will miss up to a month with a torn lateral cruciate ligament in his left knee, which he injured in the first quarter Sunday. Green, who struggled this season after four straight trips to the Pro Bowl, went down hard on his right knee when he was tackled by linebacker E.J. Henderson with 8 minutes left and was carted off the field. He sustained the same injury on Oct. 3 and sat out the following game against New Orleans. He gained 49 yards on 16 carries against the Vikings.
