SPARTANBURG, S.C. -- The Panthers suffered a scare midway through this afternoon's practice when receiver Ryne Robinson collided with safety Nate Salley on a deep pass.
The players appeared to bang knees as they both went for a pass. Salley got up after a few seconds, but Robinson did not. The team's medical personnel appeared to be checking his left knee before taking him off the field on a cart. Coach John Fox said after practice that he didn't have an update on Robinson's condition.
The Panthers have depth at wide receiver, but an injury to Robinson could impact the special teams. Robinson returned 26 kickoffs and 30 punts as a rookie last season. There's no clear-cut replacement if Robinson is out for any length of time.
