The Rugby Football Union are to provide community clubs with a financial support package.
The RFU executive team will be taking pay cuts.
Jones earns around £750,000 a year, making him the second highest paid coach in the global game, but the RFU will discuss reductions with him and the rest of England's coaching staff as cost-cutting measures. Only Bristol Bears have not disclosed how much they have asked players to sacrifice, though the other 11 clubs will cut wages by 25 per cent for players earning above an unreported threshold.
The RFU had already stated that the 2019-20 season was set to be loss-making because of the 2019 Rugby World Cup in Japan, which reduced the number of big-ticket games played at Twickenham Stadium.
"The loss will certainly now be substantially much more as we deal with difficulties comparable to services throughout the nation".
The Rugby Football Union (RFU) is facing revenue losses in the region of #45-50million over the next 18 months as a effect of the Covid-19 pandemic. In addition, combined board fees would be reduced by 75 per cent.
"The RFU's biggest asset is also a major cost and the closure of Twickenham Stadium has a significant impact on the revenues we can generate to re-invest back into the game", Bill Sweeney, CEO of the RFU said in an open letter on Wednesday. "The package includes monies ring fenced and diverted for the community game as well as additional funding".
Last week, the RFU made the decision to cancel the remainder of the English Rugby domestic season with the exception of the Premiership.

"We have modelled three potential scenarios and are working on an assumption based on a medium-term impact with a view to a return to rugby in the autumn".
