Editor's note: This is the third of five capsules explaining the NFL's new player-safety rules that were passed at last week's Annual Meeting.
WEDNESDAY: The peel-back block.
**Who: **All offensive players.
**What: **Blockers cannot initiate contact on the side and below the waist against an opponent if the blocker is moving toward his own end line; and he approaches the opponent from behind or from the side
**When: **On all offensive plays and plays in which the defensive team has gained possession.
**Where: **All parts of the field. If the near shoulder of the blocker contacts the front of his opponent’s body, the peel-back block is legal.
**How will be it be enforced: **A 15-yard penalty for unnecessary roughness?
**Reaction: “**Previously, peel back blocks were only illegal for players who lined up in the tackle box. Now, for player safety reasons, they are illegal for all offensive players.” – DawgsByNature.com.
