Seymour spent last season in a reserve role with the Panthers, making 22 tackles and breaking up four passes. His shoulder injury appears serious, however, so Corn Elder will likely fill in for him.
Seymour was thought to be dealing with an undisclosed injury, but actually just had some unofficial paternity leave. The 24-year-old struggled in the preseason opener but current sits atop the Panthers' depth chart at cornerback with James Bradberry (groin).
Seymour is not on the practice field Saturday, Jourdan Rodrigue of The Charlotte Observer reports.
Seymour started just two contests for the Panthers last season and managed a meager 22 tackles for the club. He also struggled in his first preseason contest, which doesn't bode well consider the team listed him as a starter on the initial depth chart.
