What happened: Kansas City Chiefs running back Kenneth Walker III is not expected to play Sunday after suffering a groin injury during Thursday's practice. The issue is considered minor and not a long-term concern, but the team opted to hold him out as a precaution.

Why it matters: Walker had quickly solidified the backfield after an explosive start that saw him raise Kansas City's ceiling earlier this fall. His absence tests depth as the offense adjusts without its primary ground threat.

What to watch: Kansas City will monitor Walker's progress ahead of next week's practice slate.
