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.''
