Namajunas has been given the headlining assignment due to an injury Joanne Calderwood has incurred. The UFC hasn’t disclosed any details, however, of Calderwood’s injury.
Namajunas (3-2) heads into the bout having gone 1-1 in official UFC action. After she was submitted by Carla Esparza last December, and failed to win the inaugural 115 pound title, Namajunas tapped out Angela Hill in October.
VanZant (6-1) has won three straight now in the UFC, and most recently in September, she submitted Alex Chambers.
So, there you have it. UFC FN 80 will be hosted by the Cosmopolitans’ Chelsea in Las Vegas.
