RIO DE JANEIRO – Amanda Nunes apparently had little interest in finding out what it would feel like to see Round 2 in her UFC debut. Against Sheila Gaff, the Brazilian bantamweight started fast and ended fast, earning a TKO stoppage via elbow strikes at 2:08 of the first round. The women’s bantamweight bout took place today at UFC 163 at Rio de Janeiro’s HSBC Arena. It aired on FX ahead of the pay-per-view main card. Nunes and Gaff signaled right away that theirs was not the kind of business that would likely take long to resolve. The two women met in the center of the cage and traded heavy leather in the opening seconds, though it was Gaff who initially tried to get the action to the mat. Nunes shrugged off an early attempt at a rear-naked choke, then muscled Gaff back to the floor moments later before unloading with a barrage of elbow strikes from inside the German’s guard that forced referee Herb Dean to call a stop to the bout.
