Pittsburgh Steelers quarterback Russell Wilson has been sidelined during the first days of training camp due to a calf injury sustained during a conditioning drill. Head coach Mike Tomlin emphasized that Wilson's absence is precautionary to prevent the minor injury from worsening. Wilson, who described the injury as 'nothing to panic about,' has no set timetable for his return but continues to take mental reps and assist his teammates from the sidelines. In his absence, backup quarterback Justin Fields has taken first-team reps, impressing with notable plays, including a 50-yard touchdown pass. Despite Fields' strong performance, Wilson remains the favored starter. The team is cautiously optimistic about Wilson's return, dependent on his recovery progress.
