Jiri Hudler remains property of the Detroit Red Wings and therefore the recent contract he signed in the KHL is being contested.
The National Hockey League has approached both the IIHF and KHL, seeking their intervention.
According to the NHL, Hudler is contractually obligated to the Red Wings for next season.
Hudler, a restricted free agent filed for salary arbitration, which in the eyes of the league is acknowledgement of his intent to play in the NHL next year.
Szymon Szemberg, Communications Director for the International Ice Hockey Federation tells TSN the IIHF is fully involved in the dispute.
"The IIHF has been informed by the NHL about the Jiri Hudler case. Upon, this the IIHF has informed the Russian Ice Hockey Federation about the NHL's position and the case is under investigation. As this is a transfer to an IIHF member league the player will be needing an International Transfer Card (ITC), approved by the IIHF, to complete the transfer. Only upon the IIHF's signing the ITC, the transfer would be finalized and approved," Szemberg said.
Hudler signed a two-year contract with Dynamo Moscow on July 8.
