LANDOVER, Md. (AP) — Washington Redskins rookie quarterback Robert Griffin III left Sunday's game against the Baltimore Ravens in the final minute of the fourth quarter with a sprained right knee.
Last year's Heisman Trophy winner was helped off the field after being landed on by Ravens defensive tackle Haloti Ngata at the end of a 13-yard scramble. Griffin returned to the game for four plays, then dropped to the turf on his knees and left again.
While he was being worked on by trainers on the sideline, Redskins backup quarterback Kirk Cousins entered and threw an 11-yard touchdown pass to Pierre Garcon with 29 seconds left. Cousins then ran in a 2-point conversion to tie the score 28-28, and the teams headed to overtime.
Early in the extra period, the Redskins announced that Griffin's return was doubtful.
When Griffin departed, he was 15 for 26 for 246 yards and a touchdown pass. He also ran seven times for 34 yards.
In Washington's previous game, a 17-16 victory over the New York Giants last Monday night, Griffin broke Cam Newton's single-season rookie quarterback rushing record.
