The league reportedly sent a memo to all 32 teams ordering them not to allow their cheerleaders to warm up, or do anything distracting in front of the visiting team's bench.
CBS NFL analyst Charlie Casserly broke the story last weekend, saying there were concerns around the league that some teams specifically ordered their cheerleaders to perform in front of visiting teams in hopes of distracting them from pre-game instruction.
"Some players felt they were being a little distracted," Casserly reported.
"It had nothing to do with the Patriots,” league spokesman Brian McCarthy joked to the Boston Herald, a reference to the team's recent infractions related to improperly taping opposing team practices.
“Our cheerleaders don’t do their warmups on the field,” Patriots spokesman Stacey James told the Herald. “Sorry, but the missive wasn’t directed at us.”
