LANDOVER, Md. (AP) — The referee for Carolina's 21-13 victory over Washington says there was an inadvertent whistle by the line judge on the first-quarter play when Panthers running back DeAngelo Williams scored on a 30-yard run.

According to a pool report, referee Carl Cheffers says the touchdown stood Sunday after the officials discussed the play because, "We just felt when the whistle blew, that the player would have already scored."

Redskins linebacker Perry Riley says he heard the whistle during the play "and I pulled off."

Williams, for his part, says he didn't hear a whistle and it "didn't seem like" the Redskins heard a whistle either, adding: "I don't think anybody stopped playing."
