The Baltimore Ravens' rule proposal was one of five that passed at the NFL owners meetings Wednesday. All five are designed to increase player safety.

The Ravens' rule prohibits players from pushing teammates on the line of scrimmage into the offensive formation when a team presents a punt formation.

"We thought it should be in there to begin with just because, if you're going to do it with the field goals, why not do it with the punts?" coach John Harbaugh said. "It's more of a clean-up type of a proposal."
