Cleveland Rams 1945

This is the Rams lockeroom after defeating the Lions on Thanksgiving Day 11/22/45.
Is it possible the Cleveland player #24 wore his blue jersey during the game white the rest of the team wore yellow?

I doubt it.
My question is why does his blue jersey not have the World War II War Support Effort patch on the left sleeve???

If you note the baldish player on the right hand side of the pic, he appears to have the war patch on his left sleeve and it's only a sliver of it showing. All of the other players have their arms raised in victory, so we can't tell how many players wore the patch.

As for the player in the blue jersey, my guess is he wore an old blue jersey underneath his regular yellow jersey for additional warmth. It was a bitterly cold day in Cleveland.
