On Monday, casino magnate Sheldon Adelson announced he will no longer contribute $650MM to the Raiders’ proposed $1.9 billion stadium in Las Vegas. Soon after, the Raiders issued a press release declaring that Adelson’s withdrawal would not effect their proposed move. Without Sands Corp., the Raiders were banking on the financial help of Goldman Sachs to get the stadium built, but the investment banking company is now having second thoughts about its involvement, according to a source who spoke with Ramona Shelburne of ESPN.com.

Adelson “has a longstanding business relationship with Goldman Sachs,” as Shelburne notes, but it’s not immediately clear whether that is playing a role in the firm’s trepidation. Without a significant outside contribution, it’s hard to see the Raiders getting a state of the art stadium built in the desert, and that could prevent them from making their long-rumored move.
