Glasgow rejoined West Coast Fever in 2026, after two seasons with the Melbourne Mavericks. During her second stint with the Club, she also reached her 50-game milestone in the Green Dress.
West Coast Fever General Manager Sara Francis-Bayman said the Club was thankful for Glasgow's contribution.
"We are grateful for Sasha's contribution to our Club and wish her every success in the next chapter of her career," Francis-Bayman said.
"We have a clearly defined list management strategy and throughout this contracting period, we've had to make some difficult decisions.
"While we would have liked to keep Sasha at the Club, it became clear during discussions with her management that we were unable to reach an agreement that worked for both parties.
"Sasha will always hold a special place in the history of West Coast Fever. As a premiership player and Grand Final Player of the Match, her impact on the Club, our members and the Green Army will be remembered for many years to come.
"She has been a valued member of the Club, and we thank her for everything she has given to the Green Dress."
