He is most remembered, however, for one play in 1954's
42nd Grey Cup. His Alouettes were leading by five points in the final minutes of the game, and were threatening to add to the lead with the ball on the
Edmonton Eskimos' ten yard-line. In a 1968 interview with
The Toronto Star, Hunsinger recalled,
"I was right back and the play was a sweep to the left. Their right tackle broke through and I saw I wasn't going anywhere, so I decided to pass. . . . Just as I was about to throw, someone hit me from behind—not hard, mind you—but enough to shake the ball loose. Somebody was lying across my legs and I was sick when I looked up to see
Jackie Parker taking off down the field."
Canadian Football Hall of Fame great Parker returned the ball a record ninety yards to score the game-winning touchdown. It was one of the greatest plays in
Grey Cup history.
Hunsinger recounted picking up his wife at Toronto's Royal York Hotel after the game, and heading straight home to Harrisburg with a sick feeling in his stomach. He also recalled the elation of arriving at his home to find an 800-foot-long "Cheer up, Chuck" telegram with the signatures of 21,947 Montreal Alouettes fans.
