Potieria kept pressing while Ulberg chose to stay outside and wait for the opportune moment to launch his attack. He found his opening when Potieira shot for a takedown and got caught with a thunderous left hand that dropped him. Ulberg attacked with vicious ground-and-pound and walked away even before the referee could intervene to stop the bout.Carlos Ulberg beats Ihor Potieria: What will the UFC-WWE merger company be called?Carlos Ulberg scored an impressive first-round TKO victory over Ihor Potieria at UFC on ABC 4.
