At the beginning of the 1941 season, the Bullies accepted a challenge from the defending Western Interprovincial Football Union champion Winnipeg Blue Bombers for a three-game series; the Bombers had been banned from Grey Cup contention that year due to rules discrepancies between the WIFU and the other organizations playing Canadian football at the time. The Bullies and Blue Bombers played three games, at least partially by Canadian rules (as one of the games, the deciding third game, had Winnipeg's final score as 1 point, which is not possible in the American game). Winnipeg won the first game 19-12, making the Bullies one of only two major league American football teams to have ever lost to a current Canadian Football League team. (The other American team to lose to a Canadian team is the modern Buffalo Bills, who lost to the Hamilton Tiger-Cats in 1961.) The Bullies responded, however, by defeating Winnipeg twice in the next two games, 6-0 and 31-1. Columbus won the series, 2-1.
