GREEN BAY, Wis. (AP) -- The Green Bay Packers have some questions about their depth at outside linebacker as they get ready for the Super Bowl.
Frank Zombo is back at practice, but Erik Walden sat out Friday and might not return to the practice field until next week, leaving his status in doubt for the Feb. 6 matchup with Pittsburgh.
Zombo is an undrafted free agent who became a starter in the wake of injuries. He has missed the Packers' last six games because of a right knee injury but says he had no pain Friday.
Walden was signed in midseason and has played well. He hurt his ankle in the NFC championship game victory at Chicago on Sunday.
The Packers practice in Green Bay this weekend before traveling to Texas on Monday.
