Ketlen Souza understands the fleeting nature of momentum in the cutthroat world of the Ultimate Fighting Championship.
The former Standout Fighting Tournament champion will do battle with Yazmin Jauregui when their women’s strawweight pairing helps anchor the UFC 306 undercard this Saturday at the Sphere in Las Vegas. Souza, 30, has won six of her past seven bouts. She last competed at UFC on ESPN 55, where she rebounded from a submission loss to Karine Silva, recovered from the resulting knee injury, made the decision to downshift to 115 pounds and took a three-round unanimous decision from Marnic Mann on April 27.
