Najee Harris ramps back from an eye injury and expects to play in the Chargers' season opener vs. Kansas City in Brazil, though full clearance remains uncertain. He’s been practicing with a tinted visor and limited contact; Quentin Johnston cleared concussion protocol and is on track to suit up. If Harris sits, Omarion Hampton would soak up a heavy workload. The Chargers also shuffled QB reps with Trey Lance and DJ Uiagalelei, and Herbert’s timing in practice is key to their Week 1 game plan.
