Kazee (ankle) said Sunday that the boot on his left foot is a precautionary measure to make sure he's healthy for Week 1, Brian Batko of the Pittsburgh Post-Gazette reports.
Kazee also noted that the injury itself is a "slightly sprained" left ankle that he twisted a bit during Saturday's practice. Once back to full health, he'll compete with Keanu Neal for the starting strong safety role beside free safety Minkah Fitzpatrick.
