Rangers chief executive Charles Green has threatened legal action against any players who refuse to transfer their contracts to his new company and any clubs who attempt to sign those players.
Steven Naismith and Steven Whittaker both announced their objections to transferring their contracts to newco Rangers and confirmed they will not report back to Murray Park for training this week and consider themselves free to find new clubs.
Green responded by reiterating previous warnings that he will challenge any attempts by players to walk away from his club for nothing.
He said in a statement: "It is a great pity that certain players have chosen this time to attempt to tear up their contracts and walk away from the club.
"The club is facing massive challenges in terms of its league status and the last thing the fans want to see is a dispute between the club and players.
"However, it appears that is the route several players are choosing. I can assure those players and clubs who may be interested in signing them that Rangers will seek damages for breach of contract and for inducement to break contracts.''
