Wilson (calf) was a limited practice participant Thursday, Teresa Varley of the Steelers' official site reports.
Though Wilson's limited participation represents no change from his level of activity in the Steelers' three practices since he first informed the coaching and training staff exactly one week ago that he aggravated a calf injury that first cropped up in training camp, the quarterback suggested after Thursday's session that he's noticing improvement in his condition. Per Brooke Pryor of ESPN.com, Wilson said that he's "getting closer and closer" to playing again. Though Justin Fields still appears to be trending toward a second straight start this Sunday in Denver, the Steelers aren't yet ruling Wilson out from being available for the matchup with one of his former teams. At this stage, however, Wilson appears likely to reprise the role he filled in the Week 1 win over the Falcons, when he was inactive as the Steelers' emergency third quarterback behind Fields and backup Kyle Allen.
