Pittsburgh Steelers have confirmed that their first-round draft pick, rookie tackle Troy Fautanu, will be sidelined indefinitely due to a knee injury sustained during practice. Initially downgraded to out for the upcoming game against the Chargers, Fautanu's situation has raised concerns as the offensive line faces further challenges with injuries. Several independent evaluations are expected for his condition, potentially impacting his rookie season significantly. The injury also opens the door for Broderick Jones to step up in Fautanu's absence, as the Steelers continue to navigate a series of setbacks to their offensive unit.
