They parted ways with him before a "bootcamp"; I have no idea if there is a match soon. Note that he was recruited in February, and they don't have a replacement announced.
But I doubt his claim that he could perform even though his mother was dying in cancer - and looking at recent games it seems they haven't been performing well recently https://liquipedia.net/dota2/Team_SMG#Roster - so there might be more to it.
In most jobs you would give him time off and find a temporary replacement, but I don't see how that works here. They don't have a bench, and temp-agencies might not have dota-players and I'm not convinced that anyone that is a good replacement would join on a temporary basis. I don't see any good ways of handling this.
Normal sports are still working on it, and e-sports are clearly lagging behind.
