During the Kansas City Chiefs' victory over the New England Patriots last night, Chiefs' safety Husain Abdullah intercepted a pass thrown by the Patriots' Tom Brady and scored a touchdown.
Abdullah, who is a Muslim, crouched down in a prayer position in the end zone after scoring (video below).
According to SBNation.com, that's when a NFL official threw a flag and yelled, "Unsportsmanlike conduct, going to the ground:"
However, this morning Michael Signora, the NFL’s vice-president of football communications, tweeted:
Abdullah should not have been penalized. Officiating mechanic is not to flag player who goes to ground for religious reasons.
The Washington Post reports that the NFL rulebook states: “Players are prohibited from engaging in any celebrations or demonstrations while on the ground."
Mike Pereira, former vice-president of NFL officiating and current Fox Sports commentator noted on Twitter that the rule doesn't apply to prayer:
you're not penalized for going to the ground to give praise after a TD
