Gusev agreed to a professional tryout agreement with Toronto on Friday, per CapFriendly.
Gusev racked up 13 goals and 44 points in 66 games as a 27-year-old rookie during the 2019-20 campaign. However, he totaled just four goals and 10 points in 33 appearances with Florida and New Jersey last season. The 5-foot-9 winger was a force in the KHL before coming to North America, scoring 63 goals and 215 points in his final three seasons with KHL St. Petersburg. Gusev could add some scoring depth to the Maple Leafs' bottom six if he secures a roster spot after training camp.
