Justin Fields' debut with the Pittsburgh Steelers in their preseason opener against the Houston Texans was marked by significant issues, including two fumbled snaps and multiple sacks, resulting in a 20-12 loss. Despite completing 5-of-6 passes for 67 yards and showing flashes of his potential, Fields' mistakes overshadowed his performance. Head coach Mike Tomlin acknowledged both the positives and negatives, emphasizing the dual responsibility between Fields and center Nate Herbig for the fumbles. Fields accepted accountability, stressing the need for better coordination moving forward. With Russell Wilson sidelined due to a calf injury, Fields will aim to improve in the upcoming game against the Buffalo Bills.
