Sides spent two years as the Fever's head coach.
The Indiana Fever made a major change on Sunday following a 20-win season, a playoff appearance and the emergence of Caitlin Clark onto the professional scene.
The Fever announced it had parted ways with head coach Christie Sides.
"We are incredibly thankful to Coach Sides for embracing the challenge of leading us through an integral transition period over the last two seasons, while also positioning us well for future growth," said Kelly Krauskopf, the president of basketball operations.
"While decisions like these are never easy, it is also imperative that we remain bold and assertive in the pursuit of our goals, which includes maximizing our talent and bringing another WNBA championship back to Indiana. Coach Sides was an incredible representative of the Fever and our community, and we wish her nothing but success in the future."
Sides was 33-47 in two seasons as head coach.
