Golfer Vijay Singh could lose millions from sponsorship this year.

Singh, signed a big sponsorship deal with Stanford earlier this year but the sports world reeled today, that SEC accused Robert Allen Stanford of the Stanford Financial Group, of massive fraud.

Stanford made huge investments in the sports sponsorship world, so much so that the London Times recently named Stanford the 65th most powerful person in the business of British sports.

Stanford is the sole logo that appears on Singh's hat and shirt.

It is not known at this stage how much money Singh got up front or whether he invested any money with the firm.
