It's unlikely that Minnesota Vikings linebacker Erin Henderson suits up on Sunday against the Tennessee Titans. The official injury reports are not out yet, so he's not yet listed as "doubtful," but that's been the word used by everyone involved, including Bruce Brothers of the Pioneer Press, who says it's unlikely -- or "doubtful" -- that Henderson plays after sustaining a concussion against the Indianapolis Colts in Week 2.
Henderson, 26, was diagnosed with the first concussion of his career following the team's loss to Indianapolis, and he has been out for the past two weeks, missing wins over the San Francisco 49ers and Detroit Lions. Henderson said that there "really is no timetable," for his return and that he's day-to-day.
Vikings coach Leslie Frazier said that Henderson has been cleared for limited practicing, which means he's passed some of the league's concussion tests, though it's unclear if that means he's cleared for any kind of contact. Being that the concussion was two weeks ago, it's likely the team is taking it extra slow and cautious, especially given that they're winning games in his absence.
