What happened: Cincinnati Bengals wide receiver Ja'Marr Chase left the field for a concussion evaluation following a tackle against the Jacksonville Jaguars. Chase was brought down by his facemask after catching a pass from Joe Burrow and took a secondary hit to the upper body.

Why it matters: Losing their top receiving threat would be a significant setback for the Cincinnati Bengals as they navigate a critical Week 4 matchup. The passing attack has been instrumental in establishing the team's early-season momentum.

What to watch: The team will monitor the receiver's evaluation to determine his availability for the remainder of the game.
