The Packers have dealt with plenty of injuries this year. Early in their playoff game against the 49ers, they have another. Starting cornerback Sam Shields suffered a foot/ankle injury on San Francisco’s second play from scrimmage. Shields’ foot was pinned under a teammate while several Packers tried to tackle receiver Michael Crabtree. Shields, according to Joe Buck of FOX, was in “a lot of pain coming off the field,” an exit that occurred during a commercial break.
