A day after drafting Joey Bosa, the Chargers may have a shot at another top-10 defender for their defense.
UCLA linebacker Myles Jack, who at some point may need microfracture surgery due to a knee condition, went undrafted in the first round.
San Diego holds the fourth pick of the second round, which begins Friday afternoon.
Jack's playmaking as a linebacker/safety/slot cornerback put him high on NFL draft boards, but emerging medical concerns about his knee left him undrafted after 31 picks.
Jack, 6-foot- 1 and 245 pounds, likely projects as an inside linebacker in San Diego's 3-4 defense.
