The Los Angeles Chargers will be the first NFL team to start training camp on Thursday, marking the official start of the league’s preseason calendar. Rookies and select players reported to camp last Saturday, with veterans arriving on Wednesday at the team’s facility in El Segundo, California. The Chargers, along with the Detroit Lions – whose full squad reports by Saturday – are the first two teams to have their complete rosters on site. Both teams are preparing for the NFL/Hall of Fame Game, set for July 31 in Canton, Ohio, which will open the preseason.
