What happened: Patrick Mahomes connected with Josh Downs for a Kansas City Chiefs touchdown against the Atlanta Falcons. The scoring play occurred immediately after Atlanta jumped offsides on a field goal attempt, giving Kansas City a fresh set of downs.

Why it matters: The penalty undermined an Atlanta defensive unit whose game plan aimed to disrupt Kansas City early. The touchdown also yielded immediate returns on Downs following his recent arrival via trade.

What to watch: Atlanta seeks to regroup defensively and avoid further penalties to keep the contest within reach.
