(WBEN) -- The Buffalo Bills have announced captains prior to their season opener Sunday at Chicago.
The six captains chosen by the team and named on the team's website Monday include four defensive players, but not quarterback E.J. Manuel.
Cornerback Corey Graham, running back Fred Jackson, linebacker Brandon Spikes, defensive tackle Kyle Williams, defensive end Mario Williams and center Eric Wood will have a 'C' adorned on their jerseys to signify the distinction.
They're expected to serve as leaders in on-field communication with officials.
