Officials feel that reducing the number will increase the chances of a successful bid. Carnoustie, Loch Lomond, St Andrews, Turnberry and Gleneagles are the five courses in the running so far.
Loch Lomond and Gleneagles are the two locations likely to remain in the bid because they host European Tour events. The Ryder Cup committee has made clear their desire to visit potential sites during tournament weeks to evaluate the facilities during a large-scale event. Plus, the other three are regular hosts to another prime event, the British Open.
England and Wales have also submitted proposals to bring the event to their respective home soils. Slaley Hall in Northumberland is the only course on the English bid while Celtic Manor in South Wales is the sole location mentioned in the Welsh bid.
The Ryder Cup committee expects to make its decision prior to this September's matches at the Belfry in England.
