Kareem auctioning rings for charity

An auction featuring four of Hall of Fame center Kareem Abdul-Jabbar's NBA championship rings runs through Saturday.

The league's all-time leading scorer is auctioning rings he won with the Los Angeles Lakers in 1980, 1985, 1987 and 1988, plus other game-used and autographed memorabilia from his legendary career.

Abdul-Jabbar, 71, wrote on his website earlier this month that "much of the proceeds" will benefit his Skyhook Foundation, a charity that helps kids learn about science, technology, engineering and math.
