MINNEAPOLIS— Minnesota could be without defensive end Jared Allen for this weekend's game against Green Bay.

Allen suffered a sprained right shoulder in Sunday's win over Houston, an injury he played through, and managed two of the team's five sacks. Afterward, Allen dismissed any concern about his condition by saying, "It's football. You get beat up."

But Vikings coach Brad Childress said Monday he's not sure if the 2007 All-Pro player with Kansas City will be able to recover in time to play the archrival Packers. Allen is tied for the team lead with Kevin Williams with seven sacks in eight games.
