Arnold (shoulder) was a full participant in Friday's practice and does not carry an injury designation into Sunday's game against the Bengals.
Arnold was able to practice through a shoulder injury that he picked up during the Lions' Week 4 win over the Browns, and the 2024 first-rounder has been cleared to play in Sunday's road contest. He has opened the regular season with 21 tackles (15 solo) and two pass defenses through four games.
