The Commonwealth Games could be cut from 17 to 10 sports to keep the event alive beyond 2018.
Glasgow will stage the 2014 event and the Gold Coast in 2018, but no bidders have yet come forward as 2022 hosts, a leading Games official has told the BBC.
Mike Hooper, chief executive of the Commonwealth Games Federation, said reducing the number of sports could encourage interest.
Ten sports is the minimum allowed by the Commonwealth Games Federation, with 17 the maximum.
Bids to host the 2022 showpiece must be received by March 2015 but official notes of interest must be in by the end of March this year.
So far, no notes of interest have been received.
