NFL Bans Low Blocks From Behind

Defensive players are now protected from being blocked in the knees from behind, after owners voted to change the league’s rules today.

The rules change, which seemed to be popular both with players and fans, will go into effect for the 2013 season. It will make the rule on low blocks consistent everywhere on the field, after the rules had previously banned low blocks from behind in most areas of the field but allowed peel-back blocks into defenders’ knees inside the tackle box.
