Minnesota Vikings defensive end Jared Allen believes that there is no place in the game for hits like the one San Francisco 49ers guard Joe Looney laid on Kevin Williams.
The Vikings defensive tackle avoided serious injury despite the low hit from the offensive lineman in the club's pre-season clash last week.
Allen told VikingsUpdate.com: "If a defensive player would have hit an offensive linemen in the knee like that on an interception, they're going to call it, right?
"So just because he wasn't going back toward his end zone it's not the peel-back rule, but the intent was to take his knee out.
When you intentionally duck and put your helmet or put your shoulder pad into a guy's knee, in my place there's no place for that."
The Vikings open the regular season against the Detroit Lions on September 8.
