The 20-year-old joined Stoke from Birmingham City last January, but was immediately loaned back to the St Andrew's club for the remainder of the season.
With Bosnia-Herzegovina international Asmir Begovic firmly established as Stoke's number one, Butland has had to be patient when it comes to first-team opportunities in the Premier League.
However, now that Begovic and Sorensen are fit again, Stoke appear happy to let Butland gain first-team experience elsewhere as he seeks to keep alive his hopes of being selected in England's FIFA World Cup squad.
Speaking at a press conference on Thursday, Hughes confirmed Leeds were close to securing Butland's services.
"I think there has been contact with Leeds regarding Jack Butland, and we are hopeful of a loan deal being concluded," said the Welshman.
A regular member of England's Under-21 side, Butland has one senior cap - gained in a friendly against Italy 18 months ago - and also played for Great Britain in the 2012 Olympic Games.
