Zaboev teamed up with Natalja Zabijako to compete for Estonia. They began training together on 19 September 2012. By finishing ninth at the 2013 Nebelhorn Trophy, they earned a spot for Estonia in pair skating at the 2014 Winter Olympics in Sochi. Zaboev applied for Estonian citizenship, required to represent the country at the Olympics, but in November 2013, Estonia denied his fast-track application.
