Contracts have not yet been signed, but both sides have agreed to the matchup. The 125-pound contest will take place at UFC Fight Night at TD Garden in Boston and will air on ESPN.
Barber (7-0) will be looking to keep her perfect record intact. The 21-year-old phenom has repeatedly stated her goal is become the youngest champion in UFC history, a distinction that is currently held by Jon Jones. Jones first won the UFC's light heavyweight championship at 23.
Fighting out of Milwaukee, Barber is 2-0 in the UFC. She signed with the promotion as a contestant on the Dana White Tuesday Night Contender Series in 2018.
Robertson (7-3) is just three days removed from a TKO victory over Sarah Frota at UFC 240 in Edmonton. The 24-year-old Canadian teased a quick turnaround on social media on Tuesday.
