(WNFL) - Five Green Bay Packers were limited at today's practice. That included running back Eddie Lacy, who's been playing through a sprained ankle suffered December 8th against Atlanta. Coach Mike McCarthy said Lacy looked good, and it was important for him to be on the practice field. The Packers held part of their session outdoors, to get more acclimated to the cold weather that's expected for Sunday's N-F-C Wild Card home game against San Francisco. McCarthy said the elements are reflected in the game plan. He said ball security would be a bigger concern than normal this week, due to expected single-digit temperatures predicted for Sunday. Also limited at today's practice were linebacker Nick Perry, Brad Jones, and Mike Neal -- and defensive end Ryan Pickett.
