GM ends endorsement of Tiger, can NASCAR be far behind?

General Motors Corp. and popular professional golfer Tiger Woods said on Monday that they would end their endorsement deal at the end of the year.

GM, which has warned it will soon run short of cash and is asking the U.S. government for financial support amid the economic slowdown, and Woods, who is recovering from reconstructive knee surgery, called the arrangement "mutual and amicable."

They cited a desire by the golfer for more personal time with a second baby due in late winter, as well as a need for GM to cut costs as it struggles with declining demand in the U.S. market.

Can a termination of its NASCAR program be far behind?
