(AP) 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 (3-0) 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 Buffalo (2-1) 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.
COLTS 27, BROWNS 6
INDIANAPOLIS (AP) Andrew Luck threw two scoring passes, and Indianapolis' defense did not allow a touchdown for the second straight week as the Colts beat Cleveland.
The Colts (2-1) scored on the opening series of both halves before Luck and most of the starters exited early in the third quarter. Luck finished 16 of 25 for 164 yards with one interception.
Cleveland (2-1) managed only four first downs and lined up for only three plays in Indianapolis territory against Colts starters. Four days after being named the starter, quarterback Brandon Weeden went 12 of 25 for 105 yards. Trent Richardson ran seven times for 31 yards.
