The Buffalo Bills announced six team captains Monday for the upcoming season.

Linebacker Brandon Spikes and cornerback Corey Graham were both named captains. Defensive end Mario Williams is also a first-time captain.

The three remaining captains are the same from last season: running back Fred Jackson, center Eric Wood and defensive tackle Kyle Williams.

A notable absence among the captains? Quarterback EJ Manuel, who enters his second season.

Captains are selected by voting among teammates.
