 On 18 April 2018, Brennan dropped her complaint against the AFL, after the AFL agreed to change its match review rules to remove anomalous differences between the men’s and women’s competitions, thereby ensuring greater consistency between the men’s and women’s competitions, with the AFL additionally reducing Brennan's suspension by one week.On 8 April 2019, the Bulldogs announced that Brennan had departed the club, with Brennan later saying that her decision had been "based purely around [her] need for a fresh start".Brennan signed with Richmond on the second day of the 2019 trade and sign period, becoming the first player to sign with its AFL Women's team and the first AFLW player to sign a two-year contract with a club.
