Los Angeles Chargers running back Najee Harris, who missed all of training camp because of an eye injury sustained in a fireworks mishap, is expected to start in Friday’s season opener against the Kansas City Chiefs, coach Jim Harbaugh said Wednesday. Harris was listed as having fully participated in practice. “He says he’s ready, and he looks ready to go,” Harbaugh said. In front of hundreds of reporters, Harris once again wore a helmet with a tinted visor, which he has done whenever he has practiced in front of the public this summer.
