Early career A product of Sheffield Wednesday and Sheffield United's girls' teams, Turner made her
FA Women's Premier League debut for
Doncaster Rovers Belles at the age of 16. In 2009, she left to attend
Hofstra University and play
National Collegiate Athletic Association (NCAA)
college soccer. She played two seasons at centre-back for
Hofstra Pride, making 41 appearances and scoring 4 goals. As a rookie she was named to the
Colonial Athletic Association all-rookie team. She returned to Doncaster for the inaugural
2011 FA WSL season, but was released after being informed she "wasn't good enough" to play at that level. Turner dropped down the leagues to rebuild her confidence, with spells at
Leeds United and
Sheffield, outside the
FA WSL. She was named on the shortlist for the
PFA Women's Young Player of the Year in 2015, but lost out to
Leah Williamson. In late 2016, Turner suffered a knee injury that ruled her out for 15 months.
