Invicta FC’s third Phoenix Series tournament has experienced a shake-up.

With originally scheduled participants Auttumn Norton and Erin Harpe forced to withdraw, Julia Ottolino and Gillian Noll will take their spots in the one-night bantamweight tournament that is scheduled to take place on March 6 in Kansas City, Kan., the promotion announced Tuesday. The reason for Norton and Harpe’s withdrawals were not disclosed.

Ottolino (1-0) makes her second Invicta appearance after defeating Megan Cawley by split decision in her debut last August, while this is Noll’s (1-1) first fight for the promotion.

As Ottolino was originally scheduled to face Serena DeJesus (1-1) in a reserve bout, Invicta newcomer Florina Moeller (1-1) now fights DeJesus instead.

The Phoenix Series tournament takes place over the course of one night, with the quarterfinals and semifinals being comprised of one-round affairs, and the finals being a traditional three-rounder. Matchups will be determined by random draw prior to the event.

In the main event, Lisa Verzosa (5-0) fights Julija Stoliarenko (8-3-1) for a vacant bantamweight title.
