EDEN PRAIRIE, Minn. —Erin Henderson was unable to participate in the Minnesota Vikings' practice on Wednesday due to a concussion.
Henderson, who leads the team with 26 tackles and two sacks, left last Sunday's game at Indianapolis with just under five minutes left after taking a blow while combining with Kevin Williams and Harrison Smith on a tackle. Henderson appeared dazed, and left the field with trainers and didn't return.
Following the game, coach Leslie Frazier said he thought Henderson was dealing with an "elbow or something." On Monday, Frazier said, "It turns out that Erin Henderson should be fine."
Earlier Wednesday, Frazier said he anticipated having full participation for Wednesday afternoon's practice. Henderson was at the portion of practice open to the media and even had a helmet in his hands, but was listed on the injury report as not participating. Frazier didn't speak to reporters after practice.
In the short time Henderson missed on Sunday, he was replaced by Tyrone McKenzie in the base defense and Jasper Brinkley in the nickel.
Henderson's main backup, Marvin Mitchell, has been inactive the first two weeks after missing time because of an ankle sprain.
Center John Sullivan was limited during Wednesday's practice with a continued ankle injury. He missed practice last Thursday, but returned for Friday's practice and played Sunday.
Safety Andrew Sendejo (ankle), cornerback Chris Cook (biceps), tight end Rhett Ellison (ankle), defensive end Brian Robison (elbow), receiver Jarius Wright (ankle) and Mitchell were listed as full participants for Wednesday's practice.
