The remains of the final Ohio League member Dayton Triangles, then known as the Brooklyn Tigers, and the Boston Yanks merged for this one season.
After Brooklyn Tigers owner Dan Topping announced his intentions to join the new All-America Football Conference, his rights to the Triangles' legacy franchise were immediately revoked after the season and all of its players were assigned to the Boston Yanks, who carried on the team's lineage.
In the Eastern Division, the Yanks were still unbeaten (2–0–1) as of Week Four; at their only Yankee Stadium game (October 14), they had a 13–10 lead, but the Giants tied them 13–13.
In Week Five, the Yanks' 38–14 loss to Green Bay, put them at 2–1–1, tied with 2–1–0 Washington, while in the Western race, the Rams reached 4–0 after a 41–21 win over the Bears.
In Week Seven, a blocked extra point attempt gave Detroit a 10–9 win at Boston, keeping the Lions tied with the Rams (at 5–1) for the Western lead, while taking the 3–2–1 Yanks to a game behind the 4–1 Redskins.
