Goldman Sachs is re-evaluating its relationship with the Oakland Raiders' planned deal in Las Vegas following the withdraw of Sheldon Adelson from the project.

Adelson had previously committed $650 million to get the $1.9 billion project completed but announced the removal of his stake in a statement Monday.

Adelson has a longstanding business relationship with Goldman Sachs.

A source told ESPN's Darren Rovell that the Raiders' relocation application to the NFL filed on Jan. 19 also did not include Adelson.

Goldman Sachs had been in line to help underwrite Raiders owner Mark Davis' financial commitment, but with the financial giant now re-evaluating its position and Adelson's withdrawal, the entire deal could be in danger.

With the Raiders franchise being the largest financial chip in Davis' portfolio, the inclusion of Goldman Sachs would be relied upon to carry out a deal. 

Any relocation to Las Vegas must be approved by 24 of the 32 NFL team owners. A vote is expected during league meetings in March in Phoenix.
