Cody Brundage emerged victorious from the UFC Vegas 103 co-main event, but the finishing sequence wasn't without some controversy.

Brundage started strong by landing an overhand right that stunned Marquez. He continued the attack, but Marquez managed to battle back and create a back-and-forth battle. After submission attempts from both men, "The Cuban Missile Crisis" took control with a hook and ground strikes.

Unfortunately, the UFC Vegas 103 co-main event will go under controversy, as referee Marc Smith elected to pause the fight during the back-and-forth brawling to hand back both men's mouthpieces, which had fallen. It was arguable that the pause allowed Brundage to gain momentum one last time for the win.
