Russell Wilson's anticipated debut as the Pittsburgh Steelers' starting quarterback has been postponed due to a calf injury he aggravated during practice. Despite Wilson's optimism and willingness to play, team doctors opted for caution, ruling him out for the season opener against the Atlanta Falcons. Consequently, backup quarterback Justin Fields, acquired from the Bears, will lead the Steelers. Fields, who had a mixed tenure with the Bears, completed 70.4% of his passes during the preseason but struggled with ball security. Steelers head coach Mike Tomlin expressed confidence in Fields' abilities, noting his strong performance in training camp. The Bears' trade for Fields included conditional draft picks, which could improve if Fields plays over 51% of the Steelers' offensive snaps this season.
