Farrant, 27, undertook an extensive rehab programme following the initial injury last May and returned to domestic action in April. However, she has played predominantly as a batter for South East Stars during this period, and will now miss the remainder of the Rachael Heyhoe Flint Trophy, as well as her stint with Oval Invincibles in the Hundred.
"Following surgery, she will begin rehabilitation working together with the England and South East Stars medical teams," the ECB said in a statement.
The setback is a cruel misfortune for Farrant, whose last appearance for England was a one-off ODI during the Women's Ashes in Melbourne in February 2022. She was subsequently an unused squad member during the Women's World Cup later that winter, in which England lost to Australia in the final.
