In just her fourth professional fight, the 22-year-old Shields will take on unbeaten Nikki Adler on Friday night for the women's WBC and IBF super middleweight world titles. Shields, a two-time Olympic champion, made history earlier this year when she became the first woman to headline a fight card on premium cable. Now she'll try to take another big step in a pro career that's less than a year old.
