Bohdan Shershun's former teammate Roland Gusev told the Russian media about the cause of the Ukrainian's death.
- According to Bohdan's father, it was due to a tick. Its bite caused complications on the head. But time passed, and nothing was found. Bohdan felt bad in the last days of his life - he felt weak and slept all the time. They did a puncture, and everything got so much worse," he said.
