During his time in the KHL, he served as an alternate captain for Torpedo, tallying 32 goals and 89 points in 98 regular-season games, along with three goals and 11 points in 15 postseason games.
Kovalenko is known for his versatility and ability to play in various situations, suggesting he could make an immediate impact in the NHL. However, it's essential to manage expectations as he hasn't played on the smaller North American ice before, which may require an adjustment period.
