Poker Pros Ivey, Lindgren, Benyamine and Flack Owe Full Tilt Millions.

A group of poker players owe Full Tilt Poker about $18 million, a person familiar with the situation told Card Players.

Earlier on Thursday, PokerStrategy.com reported that Behnam Dayanim, an attorney for the French investment group seeking to purchase the company, said that money owed from Phil Ivey, Layne Flack, David Benyamine, Erick Lindgren, Barry Greenstein, Mike Matusow and others could create “a serious obstacle to completion of the deal.”

Dayanim added: “This isn’t the only issue with the takeover, and the deal won’t end on any one issue — but this is a substantial item.”

According to Card Player’s source, Ivey and Lindgren both owe $4 million to the site, while Benyamine and Flack owe $2 million apiece. Matusow and Greenstein owe less.

Both Benyamine and Flack have been in debt to the site since 2007, according to the source.

Card Players were  told that the debts amounting to about $18 million are on the books, and that Groupe Bernard Tapie has known about it for months.
