The Facts: Gaffney, the Panthers’ sixth-round pick from Stanford, will undergo season-ending surgery on his left knee after injuring his knee on the first play of Friday’s practice.

Diehards Line:HC Ron Rivera said Gaffney’s surgery would be within the next week. With Gaffney out and Jonathan Stewart sidelined indefinitely with an injured hamstring, Rivera said the Panthers plan to sign a running back. We'll follow up as needed.
