League of Legends' most dominant region in recent years has suspended the professional league due to health concerns. China's cities are currently combating the Coronavirus and travel between them is one of the reasons why the decision was made.
League of Legends Pro League (LPL) is the Chinese premier circuit that decides which teams are performing the best and by extension will represent the region in international tournaments such as Mid-Season International (MSI) and World Championship. Chinese teams normally perform extremely well internationally, routinely securing either a spot in top four or winning the competition outright.
However, Season 10 is proving to be exceptionally problematic for the region. The teams were already playing seven days a week due to condensed schedule but at least they got a break during the Year of the Rat festivities. However, the break will be extended not due to the teams' needs or will but because of the health concerns.
LPL first announced the news on Weibo with the translation coming through Ran on Twitter but the confirmation in English soon came along via the official LPL account. Namely, both LPL and LDL will postpone the events planned for the week but there is no indication that the activities will resume the week after.
As you might expect these issues are caused by the Coronavirus which already resulted in Wuhan being cordoned off. Several teams' staff are currently stuck in the city , meaning that even if the virus was contained in other areas, key members of some teams would not be able to participate for the time being.
Considering that all the sporting events have been halted until March 2020, it is highly unlikely LPL and LDL resume in February. Considering the schedule for LPL, some compromises will need to be made in order to wrap up the Spring Split in time for MSI.
