At the 2016 World Men's Curling Championship, the Alexey Stukalskiy rink was slated to represent Russia, however, was replaced last-minute with Tselousov's rink after the Stukalskiy rink could not participate due to illness.

This was Tselousov's second appearance at the World Curling Championships.
