What Are the Major Sports Teams That Do Not End in the Letter “s”?

There are nine major professional sports teams based in the United States whose name does not end with the letter “s,” including the National Basketball Association’s Oklahoma City Thunder, Miami Heat, Orlando Magic and Utah Jazz; Major League Baseball’s Boston Red Sox and Chicago White Sox; and the National Hockey League’s Colorado Avalanche, Minnesota Wild and Tampa Bay Lightning. All 32 of the National Football League’s teams have mascots whose names end with a plural “s.”

In general, most teams’ names end with an “s,” since they exist in plural form. However, with the two baseball teams, “Sox” is a variation on the spelling of the word “socks” while the other teams’ exist as plural without adding the letter “s.”
