Roberts was placed in concussion protocol Saturday, Myles Simmons of the Panthers' official site reports.

Roberts, who joined the Panthers on a one-year deal in the offseason, was expected to provide some quality depth behind the big-name trio of D.J. Moore, Robby Anderson and Curtis Samuel. Even if Roberts were to miss some time, it's unlikely he'll lose spot on the 53-man roster with castoffs such as Keith Kirkwood and Pharoh Cooper behind him on the depth chart.
