Vikings coach Brad Childress said the league informed the team that Allen was being fined $25,000 for the hit in the Nov. 9 game, when Allen went unblocked and had a free run at Rodgers. Moments after Rodgers released the ball, Allen hit him high and knocked him down, drawing a roughing-the-passer penalty.
"Obviously, if it was going to happen, it was going to happen," Allen said of the fine Wednesday.
The hit on Rodgers concerned the NFL enough for it to summon Allen to New York on Tuesday to discuss his recent hits against quarterbacks.
Allen was fined $50,000 for two low hits in Week 9 on Texans quarterback Matt Schaub, whose knee injury turned out to be worse than expected. Schaub probably won't be available until the final two weeks of the season because of a medial collateral knee injury.
When Allen received that fine, he was warned he could face possible suspension if he had any future questionable hits. Allen said Wednesday that he was not planning on changing his style of play.
"No, nothing that happened was intentional. Most of those hits I was falling to the ground and I try to pull up," he said. "I'm not going to change the way I play. I'm going to play hard from snap to whistle and keep playing football."
Asked if he believed the league was getting away from the game itself, Allen said: "Obviously I have personal opinions about it, but I'll keep those to myself. The way I look at it is I told my side of the story and they told me what they thought was going on. We were able to see eye-to-eye and get a better understanding from both sides. I'm just going to go out and keep playing football the way I play football."
Rodgers said he didn't think Allen was trying to hurt him, and noted that he and Allen joked about the big hit immediately after the play.
"I respect Jared Allen," Rodgers said Wednesday in Green Bay. "I don't think that was a malicious hit at all. We actually joked about it afterwards. I know he was fined for the Schaub hit as well. In no way to I think it was intentional or did he want to hurt me. But the rules are the rules, and that's about all I'm going to say."
Childress appeared to be optimistic Allen will be able to play this week against the Jacksonville Jaguars, despite a third-degree shoulder separation. Allen is expected to be limited in practice, but he hasn't missed any games since suffering the injury.
