Perhaps it’s no coincidence that the Crimson upset their archrivals from Yale 28-21 in what partisans of the two universities call "The Game" (not to be confused with "The Big Game" between Stanford and Cal-Berkeley, also played today, sans heraldry).
Did you notice that on his jersey there is also a shield-shaped patch for "the game" itself? Perhaps it’s the world’s only armigerous football game.
I like heraldry in sport-games. It is customary in ice-hockey, where our national team is called THREE CROWNS.

The jerseys themselves are heraldic in nature:
