Nicholson (undisclosed) took part in a workout for the Panthers on Friday, Aaron Wilson of KPRC 2 Houston reports.
Nicholson signed with Cleveland as an undrafted free agent this spring but reverted to IR due to an undisclosed issue in late May. He and the Browns ultimately worked out an injury settlement, making Nicholson a free agent. He's presumably now healthy and looking to get an opportunity with another organization.
