LANDOVER, Md. — Russell Wilson raced ahead to throw the final block on Marshawn Lynch’s fourth-quarter, go-ahead touchdown run, doing just enough to get in the way of the Washington Redskins safety near the goal line.

Less than a minute later, Robert Griffin III’s knee buckled as he tried to field a bad shotgun snap, the pain so bad that he didn’t even try to recover the ball.

The last rookie quarterback standing in the NFL playoffs is Wilson — the third-round pick who teamed with Lynch on Sunday to lead the Seattle Seahawks to a 24-14 victory over Griffin and the Redskins.

“Marshawn always tells me, ‘Russ, I got your back, no matter what,’” Wilson said. “So I just try to help him out every once in a while.”

And the latest debate over the wisdom of keeping an injured franchise player on the field — when he’s obviously nowhere near his best — starts with coach Mike Shanahan, who let Griffin keep going until the QB could absolutely go no more.

“I think I did put myself at more risk,” Griffin said. “But every time you get on the field, you’re putting yourself on the line.”

Lynch ran for 132 yards, and Wilson completed 15 of 26 passes for 187 yards and as Seahawks overcame a 14-0 first-quarter hole — their biggest deficit of the season — and will visit the top-seeded Atlanta Falcons next Sunday.
