The NFL reached out to owners, GMs and coaches of all 32 teams advising them that behavior with replacement officials last week was unacceptable.
"We contacted them to remind them that everyone has a responsibility to respect the game," NFL executive vice president Ray Anderson said, according to ESPN’s Adam Schefter. "We expect it to be adhered to this weekend and forevermore."
Specifically, Broncos head coach John Fox and defensive coordinator Jack Del Rio were seen berating officials, along with 49ers head coach Jim Harbaugh, who also was very vocal toward officials in Week One.
Per the ESPN report, the last time the NFL reached out to so many teams on an in-season issue was in October, 2010 after multiple helmet-to-helmet hits had been occurring.
Anderson said that if a coach chose to act in an unacceptable manner with an official this week, “he would be flagged on the field and he would be hearing from our office in a very firm way.”
