Only days after conceding that linebacker E.J. Henderson will miss a month with two dislocated toes, it turns out that Henderson will be out even longer.

Per the Minneapolis Star Tribune, Henderson has been placed on injured reserve, ending his season.

The move creates a roster spot for left tackle Bryant McKinnie, who was suspended the first four games of the season for violating the league’s personal conduct policy.

Henderson became a force for the Vikings once the team adopted the Cover 2 defense in 2006.  Signed through 2011, he’ll earn $2.5 million in base salary this year.
