1933 National Challenge Cup

As in 1931, the ASL teams played a round robin format instead of direct knockout games.

A slight controversy ensued when a game between Boston and Fall River was called at the 78th minute with the score 0-0.

Fall River later forfeited the replay leaving Boston tied for first with Pawtucket.

The Rangers advanced on better goal average leaving Boston unable to make up the difference in a replay with Fall River or a playoff with Pawtucket.

In the West it was business as usual with the standard knockout procedure and the Stix of St. Louis making their second of what would be six consecutive trips to the national final.
