Russell Wilson

ESPN’s Adam Schefter believes Russell Wilson (calf) is “lurking” in the competition for the Steelers’ starting quarterback.

Schefter said on ESPN’s “Get Up” that head coach Mike Tomlin has not “crowned” Justin Fields as the team’s full-time starter despite a solid start to the season. Schefter suggested Tomlin could make the quarterback switch if the Steelers — who have dropped two straight games — lose to the miserable Raiders in Week 6. Wilson, Schefter said, is “within an arm’s length” of Fields as the Steelers’ starter. A poor outing for Fields, who completed just 55 percent of his throws last week against Dallas, and Wilson could end up under center for Pittsburgh.
