NBA officials are not considering a sale of the Memphis Grizzlies, because the proposed buyers have not provided enough information on where the money would come from.

Former NBA player Brian Davis leads an investment group that wants to buy a majority stake in the Grizzlies. He has declined to name the investors or discuss financing.

The sale must be approved by the NBA, and league president Joel Litvin said in a statement on Tuesday the NBA hasn't received all of the information requested from Davis and can't continue to review the purchase.

"Among other things, and despite numerous requests from the NBA, we have not been provided with important information about other potential investors, including the sources and amounts of funding that they would supply," according to Litvin's statement.

"In addition, based on the limited information that we have received, it appears that certain elements of the transaction would not comply with NBA rules. As a result, and contrary to their public statements, the NBA is not taking any action at this point with respect to the proposed transaction."

Davis leads an investment group that includes former NBA player Christian Laettner.

Davis has said he plans to invest $40 million to $55 million (euro30 million to euro41 million) personally to become controlling partner of the team, and that he and Laettner would have two to five partners.

Local minority owners of the Grizzlies decided against trying to match the $252 million (euro189 million) offer to buy out Michael Heisley's 70 percent share of the team. Under Davis' contract with Heisley, the minority owners had until Friday to match Davis' offer.

Heisley announced the proposed sale in October, saying he and Davis agreed on $360 million (euro270 million) as the total value of the franchise. The minority owners own 30 percent of the team.
