Chargers Head Coach Jim Harbaugh and quarterback Justin Herbert took the podium at The Bolt on Day 1 of Chargers Training Camp. Below are three takeaways from their media availability Thursday:

The Chargers officially announced on Thursday that they’ve placed running back Najee Harris on the non-football injury list.

Los Angeles Chargers running back Najee Harris will "likely" begin training camp on the non-football injury list after suffering an eye injury in a fireworks accident at a Fourth of July event, general manager Joe Hortiz told reporters on Wednesday.

Najee Harris is still recovering from a superficial eye injury after a fireworks incident, forcing the Chargers RB onto the NFI list to begin camp.

The Pittsburgh Steelers have running back action to fill this season after Najee Harris left for the Los Angeles Chargers. They know they can count on returner Jaylen Warren. And they hope they can count on rookie Kaleb Johnson from Iowa. But they also added another RB this offseason: Kenneth Gainwell.

The Chargers were the first team to open training camp this season, and they also have a lot of movement with their roster. Mike Williams informed the Chargers on Thursday that he plans to retire, and running back Najee Harris was placed on the active/non-football list due to an eye injury.
