NFL Passes Two Safety Rules Tuesday But Leaves Controversial Helmet Hit Ban to Wednesday VoteThe NFL caused a stir last week over some of its proposed safety changes. Voting on the rules Tuesday, owners passed two but left one of the more controversial changes for another day.

The owners outlawed peel-back blocks anywhere on the field; previously, they were illegal only inside the tackle box. A player makes a peel-back block when he is moving toward his goal line, approaches an opponent from behind or the side, and makes contact below the waist.

The penalty will be 15 yards.

“… really under no circumstances will you be permitted to block low below the waist when you’re blocking back toward your own end line,” said Rams coach Jeff Fisher, co-chairman of the competition committee.

Also banned is overloading a formation while attempting to block a field goal or extra point. Defensive teams can now have only six or less players on each side of the snapper at the line of scrimmage. Players not on the line can’t push teammates on the line into blockers, either.

The alignment violation is a 5-yard penalty. The pushing penalty is 15 yards for unnecessary roughness.

As for the more contentious proposal that drew criticism last week — one that would ban offensive players from using the crown of their helmets against defenders in the open field – NFL senior vice president of football operations Ray Anderson said the owners plan to vote on it Wednesday before the meetings end.

The potential change that has drawn the most attention – yes, even more than eliminating the infamous tuck rule, which seems to be a foregone conclusion – is prohibiting ball carriers outside the tackle box from lowering their helmets and making contact with defenders with the crown.

New York Giants owner John Mara, a member of the competition committee that has recommended the change, said there was even “a chance” a vote could be tabled until the May meetings in Boston.

“There was a spirited discussion,” Mara said, adding there was concern of how the rule would be officiated.

Broncos coach John Fox believes passing the rule will not make for a huge challenge for players.

“Right now, the simple equation is they want the helmet used for protection, not as a weapon. I think that message gets across,” Fox said. “It’s slowly gotten across as far as the passing game. Now there are rules on the table that are going to involve the running game as well.

“They will adapt. They have in the past and [they will] moving forward.”

If the rule is passed, coach of the Super Bowl winning Baltimore Ravens, John Harbaugh, said it might be difficult for officials to call.

“In all fairness, it’s going to be tough on the officials, it’s going to be tough to make that determination at live speed with one look,” Harbaugh said.

New senior director of officiating Alberto Riveron said if the offensive and defensive player are both committing the foul, it would be an offsetting penalty and the down replayed.

Riveron said the key to officiating the play is in showing the officials more plays that are legal.

“That will be a great way to train because as we know it, most of the shots we have seen are legal, most of the contact is legal,” he said. “We are trying to get that one individual situation where the head is lowered – and you can see on the field, you can see a player put his head down – and the contact is with the crown and you can see it.”

Fisher explained further about the proposed ban that it wouldn’t mean the ball carrier couldn’t “get small” and protect the football.

“…if he is going to go down to cover the football, if the shoulder goes down, we know the head goes down, we understand that,” Fisher said. ”Protecting the football is OK, providing you do not strike with the crown of your helmet, and that is what we are trying to differentiate.”

If the rule is passed, committing the foul would be a 15-yard penalty.
