ADVANCE FOR MONDAY, DEC. 23 - FILE - In this Feb. 28, 2011, file photo, former figure skater Nancy Kerrigan watches an exhibition tennis match between Pete Sampras and Andre Agassi at Madison Square Garden in New York. It's been nearly 20 years since Kerrigan was clubbed after practice by a member of a bumbling goon squad hired by Tonya Harding's ex-husband with the hope of eliminating his former wife's top competition for the U.S. Olympic team.
