Players in today’s National Football League are bigger and faster than ever — and that means devastating collisions on the gridiron.

The health issues confronting these Sunday gladiators — from concussions to blown-out knees, and the medical care provided them after they retire from the game — are explored by CBS Sports Network’s Roger Twibell and a panel of experts.

Former Kansas City Chiefs general manager Carl Peterson (now chairman of USA Football), former Chiefs quarterback Trent Green, and three-time Pro Bowl offensive guard Conrad Dobler look at the complicated issue of player health from both personal and institutional points of view and discuss the sport's future in the face of these safety concerns.
