The Steelers placed Daniels on injured reserve Tuesday due to an Achilles tear, Teresa Varley of the team's official site reports.
Daniels tore his ACL during Sunday's 27-24 loss to the Colts. The 2018 second-round pick will shift his attention toward rehab and recovery ahead of the 2025 season. Spencer Anderson is the next man up at right guard for the Steelers.
