Mathieu won't return vs. Bills due to concussion

Kansas City Chiefs safety Tyrann Mathieu won't return to Sunday's divisional-round game against the Buffalo Bills after suffering a concussion in the first quarter, the team announced.

Mathieu took a knee to the helmet from a teammate while attempting to make a low tackle on Bills quarterback Josh Allen. He briefly went into the medical tent before going to the locker room.

The 29-year-old is one of the key players on Kansas City's defense. Mathieu made his second straight Pro Bowl in 2021 after racking up 76 total tackles, three interceptions, and six pass defenses.

Daniel Sorensen will likely take on a larger role alongside Juan Thornhill, and Armani Watts should also see more snaps.
