Yahoo Sports is on the road this summer hitting camps across the country, and we're rounding up the news, updates, position battles and more you need to know.

EL SEGUNDO, Calif. (AP) — Los Angeles Chargers quarterback Justin Herbert is testing out tinted contact lenses as training camp opens. He wore them Thursday under sunny skies after trying them out earlier in the week while working with the team’s rookies.

Wide receiver Mike Williams has informed the Los Angeles Chargers that he is retiring from the NFL after eight seasons, the team announced on Thursday in the opening day of training camp.

The Los Angeles Chargers are the first NFL team to open training camp. Football season is certainly back. Somehow on Thursday, Harbaugh shared that he had met seven Presidents, four First Ladies and Pope Francis, and he said that all in the same sentence as his proclamation that he had caught 22 foul balls at MLB games.

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.

Los Angeles Chargers wide receiver Mike Williams has retired from the NFL at age 30. His agent informed the team’s general manager on Wednesday night, just before training camp began.

The Los Angeles Chargers are being encouraged to try and land WR Terry McLaurin in a trade with the Washington Commanders.

It ends an eight-year career for Williams in the place where it started. The Chargers selected the receiver with the seventh overall pick in the 2017 NFL Draft in the hopes that he would form one of the league's best duos with Keenan Allen.

That trade chip is Seth Lugo of the Kansas City Royals, a 2024 All-Star and presumptive rental thanks to his opt-out this winter. There's no guarantee the 47-50 Royals will be willing to sell, but the Dodgers would be one of many teams interested if they made Lugo available.
