Mid-Season Invitational is the second biggest event of the year for League of Legends esports and normally takes place during May each year. Now with the rampant Covid-19 in the world, it may be cancelled for 2020.
Riot Games have mostly solved problems regarding the esports events when it comes to League of Legends as they are both working remotely and the events themselves are being held online. All the major leagues are proceeding after some had paused and most major regions' play-offs are either through or close to finish.
In a normal time, this would mean MSI is closing in and we would witness the first regional clash of the year. It is different in 2020, however, due to Coronavirus and the problems any sort of gathering or international travel would pose.
Riot initially postponed MSI 2020 to July in hopes that the pandemic would tone down but the initial projections are now being questioned as well. The main reason that the suspicion arose is that Travis Gafford mentioned a rumour that there will be no MSI 2020 during the Hotline League podcast with Mark "MarkZ" Zimmerman and Yasin "Nisqy" Dincer.
Keep in mind that Gafford himself explicitly stated that this is a rumour, so it should be taken with a grain of salt. Then again, the rumour has been circling around for a while and Gafford stated he is "fairly confident" it might come to pass.
Riot Games did not officially confirm nor deny the rumours by the time of writing this article but it's possible they will address the issue sooner rather than later.
