Barber, who has been asked to stay on in his role as director of marketing and communications, and is now being tipped as a contender for the top job, will hold a meeting with representatives from Carlsberg, Nationwide, Umbro and McDonald's following the FA's board meeting next Monday.
Although Barber has been in constant dialogue with the FA Partners since Crozier's resignation last Thursday, the summit will be seen as a sign of anger and unrest within the companies, each of which has agreed four-year deals worth at least £30m.
The FA was adamant this week that none of the sponsors would pull out. However, Nationwide head of sports marketing Peter Gandolfi told Marketing that it would be "remiss of the company if it did not fully assess the impact and implications of Crozier's departure on the FA's new commercial programme".
Carlsberg and Umbro, which has signed a £150m kit deal running until 2010, have also said they are "hugely disappointed" at Crozier's departure and at the manner in which it has been handled by the FA's executive board.
In a statement issued on Tuesday afternoon and seen as an attempt to appease sponsors, FA chairman Geoff Thompson thanked the FA's "high-calibre and extremely loyal group of commercial partners" for their support.
Crozier's exit came after intense pressure from Premier League club chairmen who want to see the establishment of a Professional Game Board that will take over the running of the England team.
Barber insisted there was no threat to the cash earmarked for the amateur game under the FA's income distribution model.
"The whole basis of FA Partners is to connect the top of the game to the grass roots," he said. "That is not going to change."
