Yankee Stadium in November 1960 was the scene of one of the NFL’s most infamous and devastating hits of all time. The Giants trailed the Eagles 17-10 in the fourth quarter of a showdown for first place in the Eastern Conference. Giants QB George Shaw threw a ball across the middle to Hall of Fame halfback Frank Gifford, who caught the ball and started running with it toward the right sideline. Lurking in Gifford’s path was Hall of Famer Chuck Bednarik, a feared 6-foot-3 linebacker known as Concrete Charlie. With his shoulder, Bednarik leveled Gifford, who fell immediately and violently to the frozen grass, knocked unconscious. The Eagles recovered Gifford’s fumble and won the game – and later, the NFL Championship. Gifford, meanwhile, was removed on a stretcher and transported to the hospital, where he was diagnosed with a “deep brain concussion” and rested for several days. Gifford didn’t return to the field that season – or the next one.
