Trent Williams (John McDonnell/The Washington Post)

Left tackle Trent Williams played well against Minnesota Vikings defensive end Jared Allen in the Washington Redskins’ triumph Sunday at FedEx Field.

Allen had the Vikings’ lone sack. But it came on a play on which the Redskins’ blocking assignments didn’t leave Allen as Williams’s responsibility.

Redskins Coach Mike Shanahan said he was “very impressed” with Williams’s play, and added: “He’s played a couple of great defensive ends back-to-back weeks. Even on his one sack late in the game, it wasn’t him. We were blocking down on that side. Trent has really come into his own — very talented, just keeps on getting better and better and a very, very good leader as well.”

Said Williams: “I think I kept him fairly quiet. [There was] one mishap on a play in the first series. But other than that, I think I kept him pretty quiet. I don’t know how I did production-wise. We’ve got to grade the film out.”

Williams played the NFL’s active career sack leaders, Atlanta’s John Abraham and Allen, in consecutive games. He held Abraham without a sack. But Williams said he wasn’t getting carried away about his play.

“We’ve got a long way to go. I’ve still got [No.] 94 down in Dallas, Texas, twice,” said Williams, referring to Cowboys linebacker DeMarcus Ware. “So no patting [himself] on the back here.”
