i did read on twitter some rumours about Ceb (OG) missing TI? it's not confirmed
The rumour is that he had to do / had done eye surgery and has to stay away atleast 3 months from screen or else he will be blind.
This is taken from liquipedia page, Im pretty sure this indicate that there is a strong possibility that Ceb will not participate or else there is no point to provide a reserve player
Du "Monet" Peng - Team Aster
Lin "Xxs" Jing - Team Aster
Ye "BoBoKa" Zhibiao - Team Aster
JT - Invictus Gaming
Most of the post on social media is just a rumor. And we don't know the actual setup on the TI, Maybe they will launch the contest on separated room per team then just play there without the need to go outside. Just my opinion.
There are some rumours that the tickets will be refunded and TI could be delayed for atleast two more weeks in case if some of these players are still tested positive for covid-19 days before the first game. This is not confirmed yet, just rumours flying around
