What happened: Miami Dolphins quarterback Malik Willis admitted his play has not been good enough through the first four weeks of the season. The 0-4 Dolphins are preparing to host the Cincinnati Bengals on Sunday as they search for their first victory before an upcoming bye week. Miami is also monitoring rookie receiver Caleb Douglas, who is at risk of missing a third consecutive game with an ankle injury.

Why it matters: The Dolphins' offense has struggled significantly, ranking near the bottom of the league in passing production. The unit is trying to find its rhythm without running back De'Von Achane, who was recently placed on injured reserve. A loss on Sunday would send Miami into its bye week at 0-5 and could accelerate talks of moving future assets before the trade deadline.

What to watch: The Bengals are monitoring wide receiver Ja'Marr Chase as he makes progress in concussion protocol ahead of Sunday's matchup. Cincinnati will look to snap a two-game losing streak at Hard Rock Stadium.
