The Kontinental Hockey League says it has "not been aware of or received a complaint in relation to any incident involving Artemi Panarin in December 2011."
In a statement to ESPN, the KHL said if the league did receive any complaint, it would have investigated "as we take any allegations of misconduct incredibly seriously."
Two days ago, Panarin took a leave of absence from the Rangers, following an allegation from one of his former KHL coaches, Andrei Nasarov.
Nazarov, the former Vityaz coach, told a Russian newspaper that while his team was on a road trip to Riga, Latvia, in 2011, Panarin got into a physical altercation with an 18-year-old woman.
