Knights has competed in all 15 Netball Superleague seasons and has been a title-winning captain on four occasions.
She debuted in the 2005 season for Loughborough Lightning, joining Storm four seasons later and went on to become Wasps’ first ever signing in 2016.
Knights lifted her first Superleague title with Storm in 2014 and proceeded to lift the coveted trophy in four successive seasons, including leading Wasps’ to back-to-back league titles in the two seasons after their formation.
The 35-year-old has also represented England at under-21 level and counts a silver medal at the World Youth Championships among her honours.
“I’m so thankful for the support I have received from my family and friends through the years and now felt like the right time to call it a day and enjoy life away from netball,” said Knights.
“I’ve built my life around netball and have so much to thank the sport for. I’ve made some great friends and will certainly still be supporting them from the stands.
“Winning my first league title with Storm was really special, then to go and win two with Wasps was brilliant too, and I’ll always treasure those memories. To be the first ever Wasps player was an honour and we’re like a family now.
“I’d like to thank the teachers that encouraged me to give netball a try, even if I wanted to be a ballerina, and the coaches who saw potential in me even if I didn’t see it in myself.
