In the KHL, players can unilaterally terminate their contracts, but, according to the league's rules, a forfeiture of two-thirds of the player's salary is required to make it happen.
The only way for Radulov to free himself up before April 30 without incurring such a steep financial hit would be to acquire a go-ahead from the club. At the moment, it seems unlikely that will happen as Salavat would relinquish the KHL rights to Radulov in the process.
Radulov's current deal in Ufa runs through the 2012-13 season, but it contains an out clause to allow him to return to North America. That clause can be triggered beginning April 30. By following that protocol, Salavat would retain Radulov's negotiation rights in the future.
"Of course, [losing Radulov's rights] is not in the club's interest," Yuri Nikolayev, Radulov's Russian agent, told Russian paper Sport-Express. "This is the reason for the current pause."
Radulov and his agent are currently in talks with Salavat Yulayev and the KHL's brass in order to figure out a solution to satisfy all parties.
