Packers' Aaron Rodgers probable

Green Bay Packers quarterback Aaron Rodgers has been able to practice the past three days despite his concussion and is probable for Sunday's game against the New York Giants.

The Giants can clinch a playoff spot with a victory.

The outside linebacking position is now the Packers' biggest concern. The team is considering adding a linebacker to the roster.

Linebacker Frank Zombo is doubtful with a knee injury and is not expected to play. Linebacker Diyral Briggs is questionable with an ankle injury, and Mike McCarthy isn't optimistic about him playing. Linebacker Erik Walden is questionable with a quad, but McCarthy thinks he can play.

Linebacker Clay Matthews has missed practice time this week with a shin injury but should be able to play.

Guard Marshall Newhouse (back) and defensive end Cullen Jenkins (calf) are out.

Safety Nick Collins had a setback Friday with his rib injury and is questionable, but McCarthy thinks he will be able to play.
