The Facts: Barner is signing with the Panthers, a source tells NFL Network's Ian Rapoport.
Diehards Line:
Barner recently visited the Bills, but a season-ending torn ACL suffered by Panthers RB Fozzy Whittaker created an opening in Carolina. Barner was a sixth-round pick of the Panthers in 2013 and spent his rookie season in Carolina before moving on to Philadelphia, where he played four years. Barner will work behind Christian McCaffrey, C.J. Anderson and Cameron Artis-Payne.
