A rash of injuries from helmet-to-helmet hitting has the National Football League reviewing its approach to the practice.
Several players were injured Sunday in what some fans and observers perceived as a particularly violent weekend of football.
Former player Rodney Harrison, now a television commentator, was known for his vicious tackling style. He says suspensions are the only way to tone down the violence in the game.
"You didn't get my attention when you fined me five grand, 10 grand, 15 grand," Harrison said on NBC's pregame show Sunday evening. "You got my attention when I got suspended. ... You have to suspend these guys. These guys are making millions of dollars. The NFL [has to say], 'We're going to really protect our players. We're going to suspend these guys, not one game, but possibly two or more games.' "
That language - caught the attention of NFL executive vice president of football operations Ray Anderson - who told SI's Peter King the hits this weekend left him "profoundly disturbed."
He said comments like that were even more reason why the NFL needed to step up enforcement.
Baltimore Ravens tight end Todd Heap was knocked out of the game after a devastating head-to-head hit by New England Patriots safety Brandon Meriweather. In a massive collision between the Philadelphia Eagles' DeSean Jackson and the Atlanta Falcons' Dunta Robinson, both players suffered concussions.
And the problem is by no means confined to the professional ranks. On Saturday, Rutgers defensive end Eric LeGrand was paralyzed from the neck down after his tackle on an Army player during a kickoff return.
The very next day on the very same field in Rutherford, New Jersey, big-hitting Detroit Lions linebacker Zack Follett was carted off after a collision with the New York Giants' Jason Pierre-Paul.
After reviewing the weekend's NFL violence, SI.com'sÂ Peter King said the league must crack down hard on these devastating hits.
"The NFL has to draw a line in the sand right here, right now, and insist that the forearm shivers and leading with the helmet and launching into unprotected receivers will be dealt with severely," King wrote. "Six-figure fines. Suspensions. Ejections."
Pressure on the league to do something about head-to-head hits has been growing since NFL Commissioner Roger Goodell's testimony before Congress last year. The league is reluctant to change any rules in the middle of a season, but it apparently is ready to impose harsher punishment under current rules.
Players say hitting is what the game is about. Pittsburgh's James Harrison said when he hits an opposing player, his goal is not just to tackle him but to knock him out of the game. He wants them to hurt enough not to return that day, but not to suffer permanent injury.
"I don't want to injure anybody," Harrison said following Pittsburgh's 28-10 victory. "There's a big difference between being hurt and being injured. You get hurt, you shake it off and come back the next series or the next game. I try to hurt people."
