Since his season with the KHL's Ufa Salavat Yulayev is complete, Amirov will join the Marlies and Maple Leafs' development program this season.
The Leafs are expected to loan Amirov to the KHL for the 2021-22 campaign, according to Sportsnet's Chris Johnston.
"We look forward to welcoming Rodion to Canada in the coming weeks and having him begin working with our player development staff in Toronto," general manager Kyle Dubas said. "We also look forward to continuing to work with Ufa with his development next season. Ufa has done an excellent job guiding Rodion's development as a player to date and we are excited to work very closely with them through the summer and into the future."
The plan is for Amirov to work with the Maple Leafs' development staff both this offseason and next in Toronto, his agent Dan Milstein said.
Toronto selected Amirov with the 15th pick in the 2020 NHL Draft. The 19-year-old recorded nine goals and four assists in 39 games in the KHL this season.
