Rookie Mason McCormick to Start for Steelers

The Pittsburgh Steelers are set to start rookie guard Mason McCormick for the first time in their upcoming game against the Indianapolis Colts, following the continued absence of injured guard Isaac Seumalo. McCormick, a fourth-round pick from South Dakota State, impressed during his limited snaps against the Los Angeles Chargers, earning the starting position over Spencer Anderson. Seumalo's pectoral injury has sidelined him for four games, and although he is progressing, he remains ruled out for this week's matchup. The Steelers have relied heavily on their rookie class this season, with multiple first-year players making significant contributions. Head coach Mike Tomlin praised McCormick's 'finish mentality' and expected him to bring energy to the offensive line, which has faced challenges early in the season. This game is crucial for the Steelers as they aim to maintain their unbeaten streak against the struggling Colts.
