LANDOVER, Md. -- Washington's Rex Grossman threw for 171 yards, and Buffalo's Kevin Kolb left with concussion-like symptoms in the Redskins' 30-7 preseason win over the Bills on Saturday.
Grossman started at quarterback for the Redskins because Robert Griffin III hasn't been cleared for games following reconstructive knee surgery, and second-stringer Kirk Cousins has a sprained right foot.
Grossman completed 11 of 21 passes with one touchdown.
Tuel completed 10 of 17 passes for 63 yards.
