A day after billionaire casino magnate Sheldon Adelson backed out of a deal to build a stadium for the Oakland Raiders in Las Vegas, the arrangement continued to unravel Tuesday.

A person with direct knowledge of the proposed $1.9-billion stadium told The Times that a deal for Goldman Sachs to finance the project is contingent on Adelson’s involvement. Without the billionaire, the person said, there isn’t a deal.

The arrangement the Raiders presented to the league when they applied for relocation earlier this month centered around Goldman Sachs financing the project without Adelson.

NFL owners had been expected to vote on the move in March, but the seismic shift in the last 24 hours casts doubt on a speedy resolution to the matter.

Before Adelson issued a strongly worded statement Monday and withdrew, he had pledged $650 million toward the domed stadium in Las Vegas. The Raiders would contribute $500 million and the Nevada Legislature approved $750 million in public funds last year.

In a city Princessbet of casino moguls that is infatuated with professional football, some in the NFL are waiting to see if another billionaire will step forward to fill the financing void left by Adelson’s departure.
