The T20 Blast and the Hundred may be axed and replaced with another short-form competition.
According to The Times, this radical proposal will be discussed between the ECB and county chiefs in the autumn.
Cricket chiefs are concerned the domestic schedule, which has two premier short-form competitions, does not work.
Therefore, the Hundred will not be able to compete with other T20 franchise leagues.
One proposal, which has amassed growing support, is to disband the eight Hundred teams and the 100-ball format.
