What happened: The Kansas City Chiefs placed cornerback L'Jarius Sneed on injured reserve Saturday and downgraded rookie cornerback Mansoor Delane to out for Sunday's divisional game against the Denver Broncos. Sneed will miss at least four games due to a knee issue, while Delane was sidelined after aggravating a shoulder injury in practice.

Why it matters: The secondary injuries significantly thin Kansas City's defense ahead of a key AFC West matchup. Sneed, who re-signed on a one-year deal in June, had anchored the perimeter alongside Delane, the club's 2026 first-round pick. Kansas City now faces a test of roster depth as it defends the top seed in the conference.

What to watch: The Chiefs visit the Broncos on Sunday in Denver. Defensive end Tyreke Smith was activated from the practice squad to bolster the active roster for the contest.
