Today, communication is one of the most important segments of life without which one cannot function. With the development of the technology and IT means of communication, i.e. the transfer of information, today it has moved to the Internet, which has enabled it to be fully accelerated. The transmission of information over the Internet is mainly done through digital platforms and social networks that are used by almost all organizations today. Through them, they communicate with the public through which they convey all vital information. However, every organization faces certain crisis situations, some even on a daily basis. The last, major, crisis situation that engulfed the entire world and caught almost every organization off guard was the COVID-19 pandemic. The goal of this research paper was to show how FC Varaždin, as a sports organization, communicated with its fans during the COVID-19 pandemic and through which social networks. Using a quantitative analysis of statistical data, we wanted to determine which social network was used the most, what forms of announcements attract fans the most, and what were fans' reactions just before and during the COVID-19 pandemic. According to the obtained results, the most used social network was Facebook, through which most of the communication was carried out. NK Varaždin, as a sports organization, did not react in the best way to the emerging crisis situation and there are better ways to communicate.
