When the Raiders take on the Bills Oct. 29, they will be without running back Marshawn Lynch.
The NFL announced Friday that Lynch has been suspended one game for unsportsmanlike conduct after making contact with an official during the second quarter of Thursday's win over the Chiefs.
NFL vice president of football operations Jon Runyan issued the suspension, telling Lynch in a statement he "made deliberate contact" with one of the game officials "as he was diffusing an active confrontation between players."
Lynch was ejected from the game and assessed an unsportsmanlike conduct penalty after running onto the field from the sideline following a late hit on Raiders quarterback Derek Carr by Chiefs cornerback Marcus Peters.
Lynch, who watched the Raiders' comeback 31-30 victory from the stands, will be allowed to rejoin the team Oct. 30. Lynch does have three business days to appeal the suspension.
