International Cricket Council chiefs were due to meet again on Friday morning to continue deliberations on the future of Zimbabwe.
There have been calls for the ICC to remove the African country's full member status during their series of executive meetings in Dubai this week.
The divisive issue was put to the bottom of the agenda to prevent it impinging on other issues and then, after lengthy discussions on Thursday, adjourned until this morning.
Reports suggest Zimbabwe will not be expelled due to the inability of all members of the ICC board to reach agreement.
Expulsion would require at least seven of the 10 full member countries to concur and India, chiefly, are against it, while it is also thought West Indies and Bangladesh are inclined to side with Zimbabwe.
Should Zimbabwe's position be retained, next year's World Twenty20 in England could be thrown into chaos, with the British Government having made it clear cricket teams representing Robert Mugabe's country are not welcome in the UK.
An alternative venue may need to be found even though many arrangements have already been made and some tickets sold.
The ICC are aware, however, moving the event could lead to a boycott by teams such as England and are thought to be reluctant to consider such a step.
As a result, it is thought some delegates would prefer Zimbabwe to voluntarily withdraw from the tournament.
One major decision to emerge from Dubai on Thursday was the changing of the result of the controversial fourth Test between England and Pakistan at The Oval in 2006 to a draw.
England had originally been declared the winners after Pakistan were deemed to have forfeited the match by umpires Darrell Hair and Billy Doctrove for refusing to take the field.
Pakistan had been incensed by an accusation of ball-tampering from Hair.
The new result, following a campaign by Pakistan, will now see England's series win recorded as 2-0 rather than 3-0.
In other matters, the use of substitute fielders will be monitored much more strictly.
They will now be permitted only for injury, illness or other "wholly acceptable reasons", which will not include "comfort breaks".
There was also confirmation umpires will now have more flexibility to shorten the interval between innings in one-day internationals, a change made following problems in England's recent series with New Zealand.
The batting side will also be able to choose when one of the five-over powerplay periods should take place.
Security concerns ahead of the ICC Champions Trophy in Pakistan later this year have been discussed and will be further considered after the ongoing Asia Cup.
The ICC say "at this stage" the tournament will go ahead as scheduled in September.
