The Washington Redskins are looking at the possibility of Rex Grossman and Pat White splitting snaps at quarterback during their third preseason game Saturday against the Buffalo Bills at FedEx Field.

The Redskins have a short turnaround after their 24-13 preseason win over the Pittsburgh Steelers on Monday night and now are dealing with a foot injury suffered by their fill-in starter at quarterback, Kirk Cousins.

Cousins exited Monday’s game in the second quarter after hurting his right foot. The Redskins were calling the injury a mid-foot sprain late Monday night and saying they were hopeful it is not particularly serious. Cousins was scheduled to undergo an MRI exam Tuesday.

If he cannot play Saturday, Cousins would join starter Robert Griffin III on the sideline. Coach Mike Shanahan has said he intends to withhold Griffin from the entire preseason as Griffin works his way back from knee surgery in January. Griffin was examined Monday by orthopedist James Andrews, who performed his surgery. Andrews is to examine Griffin again after the preseason before making a recommendation about Griffin’s playing status for the regular season.

Shanahan was asked by a reporter late Monday night about the possibility of Grossman and White playing a half each Saturday against the Bills and said, “I think you answered your own question.” But Shanahan added: “You are jumping ahead. I can’t make that statement.”

Redskins players have Tuesday off. The team is scheduled to practice Wednesday and Thursday at its training facility in Ashburn.
