It appears Minnesota Vikings end Jared Allen is in the clear with his ailing back.
An NFL source said on Tuesday that an MRI on Allen's back showed no structural damage and he should be fine to play in this week's critical game against Chicago.
Allen reported back spasms after Sunday's loss at Green Bay, leading the team to put him through more tests as a precaution.
He acknowledged after the game he also has been battling a torn labrum in one of his shoulders that may require surgery but said he doesn't feel it's impacting his play.
"Honestly, my hats off to our training staff," said Allen, who also has appeared on the injury report with neck and groin problems this season.
"I've been banged up a lot this year from (my) groin to my shoulder. They've done a great job of getting me there. I've never had to miss a practice for it. I've never had to miss a game for it. They do a good job of keeping it healthy and, heck, I think my AC joint is probably the worst part about it."
Allen was credited with 1½ sacks against the Packers, giving him 8½ for the season -- well off the pace when he recorded 22 sacks in 2011.
