MIAMI (AP) _ Wayne Huizenga has received numerous offers for the Miami Dolphins, including a proposal worth about $800 million from an undisclosed buyer, a source close to the team owner said Thursday.

``There have been a multitude of offers to buy the whole deal,'' said the source, who did not want to be identified.

Huizenga, 62, announced in June that he wanted to sell a minority stake for estate purposes. He has received no serious offers from prospective minority partners, the source said.

The $800 million offer was first reported by ESPN.com, which said the bid came from a businessman who made his fortune in a dot-com company. Huizenga and his aides have doubts about whether the bid is serious, the source added.

A sale of the entire franchise would likely include Pro Player Stadium, which Huizenga also owns.

Huizenga could not be reached for comment. Dolphins president Eddie Jones reiterated that Huizenga wants to sell only a minority interest.

``I'm telling you what Mr. Huizenga told me: He said he has entertained no offers to sell the team in its entirety,'' Jones said.

Huizenga, who sold the Florida Marlins last year, has repeatedly said he plans to keep a majority share in the Dolphins. He bought 15 percent of the Dolphins and 50 percent of the stadium from team founder Joe Robbie's family in 1990, then became sole owner in 1994. Total cost of the purchases was $168 million.

Last year Daniel Snyder bought the Washington Redskins for $800 million, a record price for any sports franchise.
