What happened: Guard Trey Smith exited Sunday's game to undergo evaluation for a concussion. Smith headed to the locker room during play, with Mike Caliendo taking over at right guard.

Why it matters: The injury thins Kansas City's offensive front, which was already navigating multiple absences across the unit. Smith topped Week 6 run-block grades at 91.0 and has been an essential anchor along the interior line.

What to watch: Smith must clear the NFL's concussion protocol before returning to competition. Further updates on his availability are expected following postgame medical testing.
