LANDOVER, Md. (AP) Washington Redskins rookie quarterback Robert Griffin III reinjured his right knee in the fourth quarter of Sunday's playoff game against the Seattle Seahawks.
Griffin's heavily braced right knee buckled badly as he tried to field a bad shotgun snap on a second-and-22 at Washington's 12-yard line. He lay on the ground, unable to recover the ball as the Seahawks pounced on it.
Griffin walked off the field under his own power, but the Redskins announced he would not return.
Griffin was playing in his third game since spraining his right knee about a month ago against the Baltimore Ravens.
The No. 2 overall pick and last year's Heisman Trophy winner set several rookie quarterback record this year. He had 10 completions on 19 attempts for 84 yards with two touchdowns and one interception when he left the game. He also had five carries for 21 yards.
