PHOENIX (AP) - The NFL concentrated on player safety on the second day of the owners meetings, yet didn’t vote on the most contentious rule proposal.

Concerned with how it will be officiated, owners delayed voting Tuesday on a rule change that would ban offensive players from using the crown of their helmets against defenders in the open field.

After approving two other rule changes to enhance player safety, they stalled on the more contentious issue. 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.”

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.

“There were injuries, yes,” Fisher said. “Talking to coaches and the players, it’s just not something they look forward to doing. It’s like, `Oh, we scored again? We have to go out there and protect, kick an extra point or try?’”
