Per ESPN.com's Adam Schefter:
The NFL reached out to the owners, general managers and coaches of all 32 teams this week to advise them that the type of on-field behavior they witnessed last weekend will not be acceptable this weekend.

Coaches including coach John Fox and defensive coordinator Jack Del Rio of the Denver Broncos, along with San Francisco 49ers coach Jim Harbaugh, were spotted berating officials in a way unacceptable to the league office.

"We contacted them to remind them that everyone has a responsibility to respect the game," NFL executive vice president Ray Anderson said Thursday night. "We expect it to be adhered to this weekend and forevermore."

Respect the game? Does the NFL respect the game when it uses these refs? Now who's asking the questions?
