DETROIT -- General Motors, struggling to conserve cash, says it will end its endorsement deal with Tiger Woods at the end of the year, according to USA Today.

GM said Monday that it is looking to save money, and the world's No. 1 golfer wants more personal time as he and his wife expect their second child.

Woods has endorsed GM products around the world and has been closely tied to its Buick brand in the United States, Canada and China. He has carried the Buick brand on his golf bag since 2000, and his most recent promotion was to caddie for a contest winner for nine holes at Torrey Pines, where Woods won the U.S. Open this summer for his 14th career major win.
