After losing one undefeated opponent, Tonya Evinger has now agreed to meet another.

Evinger was originally expected to face Ketlen Vieira at September’s UFC Fight Night 137 in Brazil. But with injury forcing Vieira out of that matchup, Aspen Ladd (6-0 MMA, 1-0 UFC) has agreed to face Evinger (19-6 MMA, 0-1 UFC), instead, and the matchup has been pushed back two weeks to the blockbuster UFC 229 card on Oct. 6 at T-Mobile Arena in Las Vegas.

MMAjunkie today learned of the new booking from multiple people with knowledge of the agreement who spoke on the condition of anonymity because the promotion has not formally announced the new contest.

Evinger is currently ranked No. 6 in the latest USA TODAY Sports/MMAjunkie MMA women’s bantamweight rankings, while Ladd checks in at No. 14.

UFC 229 features the much anticipated lightweight title match between current champion Khabib Nurmagomedov and former title holder Conor McGregor in the pay-per-view headliner. A complete bout order has yet to be revealed, but prelims air on FX and stream on UFC Fight Pass.

Evinger, 37, a women’s MMA pioneer and former Invicta FC bantamweight champion, looks to fight for the first time since her UFC debut, a July 2017 loss to Cris Cyborg in a failed bid for the UFC women’s featherweight title. Evinger hoped to return earlier this year, but a knee injury forced her to the sidelines until now.

Meanwhile, Ladd, 23, is unbeaten through the first six fights of her professional career, including a UFC win over Lina Lansberg following a perfect 5-0 run under the Invicta FC banner.

With the addition to the card, UFC 229 now includes:

Champ Khabib Nurmagomedov vs. Conor McGregor – for lightweight title Tony Ferguson vs. Anthony Pettis Dominick Reyes vs. Ovince Saint Preux Derrick Lewis vs. Alexander Volkov Felice Herrig vs. Michelle Waterson Sean O’Malley vs. Jose Quinonez Jussier Formiga vs. Sergio Pettis Scott Holtzman vs. Alan Patrick Yana Kunitskaya vs. Lina Lansberg Nik Lentz vs. Gray Maynard Ryan LaFlare vs. Tony Martin Tonya Evinger vs. Aspen Ladd
