New England defensive end Andre Carter didn’t have a single solo sack at FedEx Field last season as a member of the Redskins. Returning to Washington, he posted a big one Sunday afternoon, adding to his team-leading total.

“This season in itself has been such a blessing,” Carter said. “The opportunity to do what I do and play with some great men on this football field. Overall, that was a way to contribute, to try to put points on the board and I did my job.”

Carter now has 10 sacks on the year — 3 1/2 more than any Washington player. His lone sack Sunday put the Patriots on the scoreboard first.

In the opening minutes, the Redskins faced third and nine from the Washington nine-yard line. Quarterback Rex Grossman waited too long in the pocket, and Carter beat left tackle Willie Smith. Carter sacked Grossman in the end zone, jarring the ball loose. Vince Wilfork recovered for the game’s first score.

In the next quarter, however, Carter had a costly penalty. Grossman threw a short pass toward running back Evan Royster that was intercepted by Devin McCourty. Carter, though, was called for roughing the passer because officials felt he hit Grossman below the knees.

“There was no intention of going low,” Carter said. “I thought it was a good hit. The league has definitely been involved in protecting quarterbacks, which I understand. That was my fault, and I will try better to not put our defense in that situation.”
