PITTSBURGH (AP) — Justin Fields threw for a touchdown and ran for another and the Pittsburgh Steelers topped the Los Angeles Chargers 20-10 on Sunday. Pittsburgh improved to 3-0 for the first time since 2020 behind another efficient performance from Fields, who completed 25 of 32 passes for 245 yards, including a 55-yard touchdown pass to Calvin Austin III midway through the fourth quarter that broke it open. Fields also added a 5-yard touchdown run and is quietly making a compelling case that he should be the starter even after Russell Wilson's injured calf heals.
