After one takedown attempt early in the fight, Frank Mir decided to stand and trade with the UFC heavyweight champion Junior dos Santos. That was not a wise idea. JDS battered him around the cage late in the first round and again in the second, finally getting the stop after hurting Mir so badly that he couldn't get up. The bout was brought to a merciful end at 3:04 of the second round.
Mir closed the distance early and scooped up a single leg right away. He attempted to pull guard with it but JDS escaped. Dos Santos landed a nice body shot, and Mir whiffed on a head kick. Mir decided to throw some keg kicks. Dos Santos mixed up the body shots well enough to be able to take Mir by surprise land an uppercut. The body work was pretty effective. Dos Santos wobbled him with a big right and poured it on late, but the round ended.
Dos Santos landed a nice straight right as the first significant blow of round two. He then rocked him with a big right and Mir went down, but he let him up. He might have been playing possum a bit. Mir got poked in the eye but Herb Dean didn't give him a stop. JDS continued to have his way with the standup, and Mir didn't do anything to try and change that. Mir went back to the kicks that were somewhat effective in the first round. Mir went down from a big right and Dos Santos swarmed. Mir looked to be done, but JDS played it safe and wanted him to get up. The only problem was that he couldn't, and one more big hammerfist forced the referee to stop in.
Dos Santos picked up the title by knocking out Cain Velasquez at UFC on Fox 1 last November. This was his first title defense. Mir stepped in for Alistair Overeem when Overeem was removed from the card due to a failed drug test. He entered the bout on a three-fight winning streak.
