Bengals left guard Andrew Whitworth sustained a concussion during Wednesday's practice, the team site announced.
As a result, Whitworth was unable to practice Thursday. Having a mid-week concussion certainly puts his playing status in doubt for Sunday's game against the Vikings.
If Whitworth is unable to play Sunday, the Bengals will likely turn to Kevin Zeitler to man the left guard spot against the Vikings.
