Amirov was just 21-years old, and was battling a brain tumour for the past two years, and unfortunately that battle has now come to an end.
He was a first-round pick of the Leafs back in 2020, and while he didn't make it to the NHL, he clearly had an impact on many people around him in America and Russia.
Despite never making it to the NHL, Amirov was clearly a fantastic person and had a positive impact on all those he came into contact with, so we send condolences to his friends and family on this sad day.
