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 win over the Bills on Saturday.
Grossman got the start 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.
Kolb started for the Bills after first-round pick EJ Manuel hurt his left knee in the Bills' previous game. But Kolb was kneed in the back of the helmet after a scramble in the first quarter, leaving undrafted rookie Jeff Tuel as Buffalo's only healthy quarterback.
Tuel completed 10 of 17 passes for 63 yards.
