GREEN BAY, Wis. (AP) -- Packers fans may need their scorecards to see who's playing running back in Thursday night's game with Tennessee.
Rookie Brandon Jackson had been expected to fill in for ailing starter Vernand Morency, but Jackson suffered a concussion in practice Sunday and may not play.
Coach Mike McCarthy says if Jackson can't play, he'll start Noah Herron, and rookie Deshawn Wynn should also see substantial playing time.
Brett Favre joked that there's only one good solution -- throw the ball more.
