The Associated Press | July 16, 2014 Head injuries force Holiday to end career Share LOS ANGELES -- UCLA guard Lauren Holiday is ending her college basketball career after just 12 games in two seasons because of repeated head injuries. The younger sister of former Bruins star and NBA player Jrue Holiday, Lauren Holiday averaged 3.3 points, 3.8 rebounds and 1.3 assists. Holiday, a redshirt freshman, will remain with the team as an undergraduate assistant and continue pursuing a sociology degree. Coach Cori Close made the announcement Tuesday. Holiday, from nearby Calabasas, began her career at UCLA in 2012-13, when the first of four head injuries ended her first season after she played in just three games. Last season, Holiday sustained three other head injuries and a broken nose. Holiday says not being able to play basketball is going to be ''tremendously hard'' because it's what she's done most of her life. 2020 US men's Olympic basketball team: Roster, college careers The 12-player roster for the 2020 U.S. men's Olympic basketball team features three former Kentucky players, a pair of UCLA Bruins as well as representation from 7 other DI college basketball programs.
