PITTSBURGH (AP) — Justin Fields will likely make his third straight start at quarterback when the Pittsburgh Steelers host the Los Angeles Chargers. Coach Mike Tomlin says that Fields will practice with the starters during the early portion of the week while Russell Wilson continues to rehab from a calf injury he aggravated a few days ahead of the season opener earlier this month. Tomlin praised Fields for his decision-making and his demeanor but stopped short of saying Fields would be the full-time starter whenever Wilson is cleared to play.
