The Bills' star defensive back is in concussion protocol.

The Buffalo Bills advanced to the AFC Divisional Playoff Round with a huge win over the Pittsburgh Steelers yesterday. 

However, as they prepare to face the Kansas City Chiefs, one of their key players is struggling with a concussion.

According to ProFootballTalk, Bills cornerback Taron Johnson is presently undergoing NFL concussion protocol. 

 Johnson recorded two tackles and a forced fumble in Monday's Wild Card game against the Steelers, and he finished the regular season with 98 tackles, eight passes defended, one sack, three forced fumbles, and a fumble recovery.

Johnson received Second-Team All-Pro accolades for the first time in his career.

 If Johnson is unable to play against the Kansas City Chiefs on Sunday, it will be a significant blow to the defense.

 While the Bills have defeated the Chiefs three times in a row during the regular season, they have also lost two consecutive postseason meetings.

Ironically, the Bills have done better against the Chiefs in Kansas City than at home. 

According to Pro-Football-Reference, they have not won a home game against the Chiefs since 2012.
