CARSON (AP) — Alvin Kamara ran for a 50-yard touchdown and the New Orleans Saints beat the Los Angeles Chargers 13-7 on Sunday night. Safety Dexter McCoil intercepted Ryan Nassib’s fourth-quarter pass and returned it 99 yards for the Chargers’ lone touchdown. With just a six-day turnaround to the all-important third preseason game, both the Chargers and Saints gave their starting quarterbacks the day off.
