 Pereira said the rule came up in games about 12 to 15 times per season and explained that despite its unpopularity, the competition committee had been unable to come up with a better rule.The tuck rule was also enforced in an NFL playoff game on January 9, 2011, between the Kansas City Chiefs and the Baltimore Ravens.After this game, Mike Pereira, the former NFL vice-president for officiating, stated that he was no longer in support of the tuck rule.
