Hampden Park has been the home of the Scotland national team since 1906
A decision on whether Scotland will play their home matches at Hampden or Murrayfield from 2020 has been delayed.
The seven-strong Scottish FA board met for several hours on Wednesday, but were unable to come to a conclusion.
Proposals were submitted in July by Queen's Park - the League Two club who own Glasgow's Hampden - and by Scottish Rugby, who want to host games in Edinburgh once the lease expires.
Both parties have been asked to provide more information within the next week.
Scottish FA chief executive Ian Maxwell said the decision "will have a significant bearing" on Scottish football and that the additional information will "allow a final decision to be made".
The board had final tours of Hampden and Murrayfield on Tuesday.
They also met to discuss the issues, having spent several days poring over thick dossiers on each bid.

The Scottish FA has an option to renew their lease on Hampden - the national team's home since 1906 - but they commissioned a feasibility study to assess all the options.
After rejecting a proposal in January from Celtic and Rangers to share hosting of internationals and domestic cup matches, the choice boiled down to remaining at Hampden or moving to Murrayfield.
League Two club Queen's Park agreed in principle in March to sell Hampden to the Scottish FA - a development thought to make it more likely the governing body would keep hosting games there.
But various hurdles - including the cost of such a deal - do not make it a foregone conclusion.
