Smith-Schuster (concussion protocol) won't play Sunday night against the Chargers, Matt McMullen of the Chiefs' official site reports.
With Smith-Schuster out and Mecole Hardman (abdomen) having been placed on IR, look for Marquez Valdes-Scantling (illness) to be busy Sunday, assuming he's active. Meanwhile, Kadarius Toney, Justin Watson and Skyy Moore also are candidates to see added work, with Toney likely to absorb a good portion of Hardman's previous responsibilities.
