The Panthers placed Smith-Marsette (undisclosed) on the practice squad injured list Tuesday, Darin Gantt of the team's official site reports.
The nature of Smith-Marsette's injury isn't clear. However, the 2021 fifth-rounder is now not eligible to be elevated from the practice squad to the active roster for at least the next four games. Smith-Marsette has not seen regular-season action since 2024 as a member of the Giants.
