Which of the following roles were uncommon among players of the first modern hockey games?

During the early development of modern hockey, which began in the late 19th century, the notion of professional athletes was not prevalent. The game was primarily played by amateur players, often in community settings, where it served as a social activity and a form of entertainment. Communities would gather to support their local teams, and many of the players were part of these communities themselves.

The majority of those involved in the initial hockey games were young boys and amateur players; they were not being paid to play, which is a defining characteristic of professional athletes. The establishment of formal leagues and the transition to professional players did not occur until later in the history of the sport. Therefore, the role of professional athletes was uncommon during the first modern hockey games.
