What happened: Denver Broncos wide receiver Jaylen Waddle aggravated a previous chest injury on a reverse during last Sunday's 30-16 road victory over the Arizona Cardinals and did not return, per @RapSheet. Listed as questionable, Waddle will have his availability for Sunday's game against the Kansas City Chiefs determined by how practice progresses this week.

Why it matters: With Jaylen Waddle emerging as a key piece of the Broncos' passing attack, any missed time would test an offense entering a marquee AFC West showdown. Fifth-seeded Denver faces top-seeded Kansas City with less than $5 million in salary cap space available ahead of the Nov. 10 trade deadline.

What to watch: Denver's daily practice participation reports from Wednesday through Friday will determine Waddle's game status ahead of Sunday's kickoff against Kansas City.
