The Chargers signed four of their six draft picks on Thursday.
Linebacker Manti Te'o, wide receiver Keenan Allen, linebacker Tourek Williams and quarterback Brad Sorensen all agreed to four-year contracts.
That leaves offensive tackle D.J. Fluker, their first round pick, and cornerback Steve Williams as the only players yet to sign a deal.
Rookie Mini-camp starts Friday at Chargers Park. Workouts are closed to the public and media.
