Packers wide receiver Greg Jennings is worried about playing on the sod at Solider Field on Sunday. Jennings called the grass at Soldier Field "probably the worst in the league," but added that the surface can "only play so much into the game if you allow it to." He watched Chicago's 35-24 win over Seattle in the divisional round on television, and noticed players slipping "on a couple routes," but added "that's going to happen regardless of what field you're on if you're in that type of climate."
