If you are speaking about Miroshnichenko, he does not have a contract with Vityaz. To understand the case, you need to know how Russian hockey works. Players starting attending a hockey school at the age 5 or so. They finish this hockey school at 16 I believe. Exactly at that age, they use to move to America, Canada. But if staying in Russia & changing a club (like Miroshnichenko is doing), his new club is obligated to pay a fee to the previous club (hockey school developing a kid) - it is some kind of RFA rights. That fee is stipulated generally by the Russian Hockey Federation. According to media reports, Vityaz does not agree with a sum of the fee, so paperwork is being done now. So, some commission of the Russian Hockey Federation is considering the case. Miroshnichenko is proposed to play the MHL this season. So, he needs to sign with Avangard (their MHL team Omskie Yastraby) before Dec 27th if he wants to play the MHL in 2020-21. It is the trade deadline in the MHL.
