First, a run-down of the particulars:
- A limit of 128 pounds is observed for this list.
- The inception of the title was the first fight in the division between two undefeated fighters.
- The linear championship for this weight class has taken a particularly strange journey. As with almost all divisions, it is arguable where one should start the lineage. However, after exploring several different pathways at the beginning, the end result (as of 2022) is the same. Missing divisional info from Tavares’ fights in the early 2000s is an issue in verifying lineage. Furthermore, there is an alternate path in the mid 2010s where Honchak is cleared from the record after lengthy inactivity, giving Jennifer Maia the title in December 2017, about a week AFTER Honchak would’ve lost it to Murphy. Not to mention, Honchak also lost in the TUF household just prior in a “pro exhibition”. If we include Modafferi/LaRosa in 2010 (catchweight bout: 130lb, though Modafferi weighed in at 128), then the lineage takes a completely different route leading to Shevchenko (as of 2022).
- Recordkeeping and regulations (weight classes) were notoriously bad for Women’s MMA. As a result, we may update this list if new info presents itself.
