Mike Ashley and Rangers face hearings before the Scottish FA in March over the Newcastle United owner's possible breaches of dual interest rules.
A procedural hearing at Hampden on Tuesday set a date of 2 March for a full hearing into two charges against Ashley over his interests in two clubs.
Rangers will appear at a separate hearing on 16 March to answer three charges against the football club.
Ashley owns 8.92% of the Scottish Championship outfit's shares.
He was accused on 15 December of not acting in the best interests of football and of breaching a rule relating to holding power over two clubs.
The Sports Direct founder was recently refused permission by the SFA to extend his Ibrox shareholding to almost 30%, having previously signed an agreement that limits him to 10%.
His two close business associates, Derek Llambias and Barry Leach, recently joined the Rangers board and Ashley has loaned the Ibrox club money for working capital.
