EAST RUTHERFORD, NJ - Coach Tom Coughlin said this morning that defensive end Dave Tollefson will be out "a while" because of the sprained medial collateral ligament he suffered in the loss Sunday to the Philadelphia Eagles.
The team will likely wait to see how Tollefson progresses before determining whether to place him on injured reserve.
Tollefson has 10 tackles (including five solo, one for a loss and a half-sack) and has been one of the Giants' best special teams players. His 13 special teams tackles (nine solo) are second on the team to Chase Blackburn's 14. He also has forced fumbles on both defense and special teams.
Wide receiver Mario Manningham has a heel injury, but will try to practice today.
The other players listed on the Giants' preliminary injury report are defensive end Osi Umenyiora (knee), who practices on a limited basis or not at all on Wednesday, offensive linemen Shaun O'Hara (foot) and Shawn Andrews (back), and wide receiver Devin Thomas (hamstring).
