"I have a problem when we talk about player safety in this league and we have a clear case of a guy intentionally trying to hurt a guy and we do nothing about it," said Allen, who has been fined several times in the past for hits. "We pat him on the back and say it's OK."
The collision occurred on a running play to the right. Williams was about 10 yards away from the play and started back to his right when Looney went down and hit him in the knee. An MRI revealed no ligament damage to Williams' knee and the Vikings said he had a significant bruise and a hyperextension. Frazier said on Tuesday that Williams was listed as day to day.
Meanwhile, the NFL will keep a close eye on hits to the knees of defenseless players this season, with the possibility of extending the rules protecting such players.
