NFL owners passed a resolution at their meeting Tuesday in Washington requiring teams to appear on the HBO program “Hard Knocks” if asked, with certain exceptions.

According to the league, the first step in the annual process of choosing a team to appear on the show would be to ask for a volunteer. If there is none, the league would create a pool of teams that would be required to appear if selected.

The teams exempt from such a mandatory appearance are those with new head coaches, those that reached the playoffs in either of the previous two seasons and those that had appeared on the show within a 10-year span.

“So if you don’t want to be on the show,” one league official said, “make the playoffs.”

The Cincinnati Bengals appeared this year on the series, which provides viewers with a behind-the-scenes look at the featured team during training camp.
