New York Giants running back Rashad Jennings said Monday that he suffered a sprained MCL in the team's Week 5 victory over the Atlanta Falcons.

Jennings doesn't anticipate the injury requiring surgery, but expects to miss some time. Head coach Tom Coughlin, meanwhile, said he is going with a day-to-day designation for Jennings until he's told otherwise.

Wouldn't be surprised if Jennings sits out until after the bye week, especially if the run game functions w/o him. — Patricia Traina (@Patricia_Traina) October 6, 2014

Rookie Andre Williams replaced Jennings, and will likely continue to carry the load in his absence. Williams rushed 20 times for 65 yards and a touchdown in the victory.

The Giants begin a two-game road stretch Sunday against the Philadelphia Eagles.
