England are questioning how Stanford (left) has run his tournament
England cricket chiefs are to carry out a review of the $20m Stanford Super Series, BBC Sport understands.
The Twenty20 tournament has attracted criticism for its poor floodlights and slow wicket as well as American backer Sir Allen Stanford's conduct.
"I'm hearing there are serious concerns from the ECB at the manner in which the tournament has been staged," said BBC cricket correspondent Jonathan Agnew.
The ECB signed a lucrative deal with Stanford last June for five matches.
But the inaugural winner-takes-all series has been marred by controversy since it began last weekend.

Stanford was forced to apologise for his behaviour during England's opening victory over Middlesex on Sunday after he was pictured with Matt Prior's wife seated on his lap and his arms around other wives and girlfriends.
Captain Kevin Pietersen then expressed concern about the standard of the pitch and the floodlights at the Antigua ground built by Stanford.
England will face the Stanford Superstars - led by West Indies star Chris Gayle - in a showpiece finale on Saturday, a match which will see each member of the winning team become an instant dollar millionaire.
We will be fine for Saturday - Pietersen
But a stomach bug, which has sidelined four England players, has further dampened spirits with Pietersen saying he "wants to get [the week] over with".
All-rounder Andrew Flintoff, meanwhile, referring to the incident involving Stanford and the wives and girlfriends, told BBC 5 Live: "It was quite bizarre, wasn't it?
"I think he's accepted he was out of order, he's apologised and we move on from there."
West Indies batsman Ramnaresh Sarwan, who will figure for the Superstars, added Stanford would not have meant to cause offence, and that he "generally just tries to be nice to everyone".
Team-mate Paul Collingwood, Pietersen's predecessor as one-day captain, said he did not know what aspects of the week in Antigua the ECB review would focus on.
"From our point of view, it's run pretty smoothly. The facilities we've had to practice and to train in have been excellent.
