In January 2010, Lesnar revealed on ESPN's "SportsCenter" that he was scheduled to make a return to the UFC in the summer. A match between Frank Mir and Shane Carwin took place on March 27 at "UFC 111" to determine the Interim Heavyweight Champion and Lesnar's next opponent. Shane Carwin defeated Mir via knockout in the first round, becoming the new Interim Champion. After the fight, Lesnar came into the ring and stated, "It was a good fight but he's wearing a belt that's a make-believe belt. I've got the real championship belt". Lesnar faced Carwin at "UFC 116 on July 3" to unify the heavyweight titles. Early in the first round, Carwin knocked Lesnar down with a punch, gave him a cut above his left eye and used a ground and pound attack the rest of the round. In the next round, Lesnar was able to take Carwin down, attain a full mount, then move into side-control and finish the fight with an arm-triangle choke. With the victory, Lesnar became the undisputed UFC Heavyweight Champion, earning his first Submission of the Night and giving Carwin his first loss. The win also tied a UFC record for most consecutive successful UFC Heavyweight Championship defenses.
