As we can see from that second link, the woman in Shannon's photo certainly does look a lot like Anna Alminova, and Alminova is/was definitely sponsored by Nike.

For those who don't know, Alminova was recently busted for biological passport irregularities, with all results since February 2009 to be scrapped:
