Concepcion came out with furious assault. He was taking the fight to Marquez within seconds and had the Mexcian fighter on the run. In the second minute, Concepcion caught Marquez with a very big counter hook to put him down. Marquez beat the count and made a decision to stand and trade punches. Concepcion appeared be to much bigger and stronger than his opponent. Concepcion was laying the punches on Marquez against the ropes when the Mexcican boxer landed a counter hook of his own and put the champion down at the bell. Concepcion quickly jumped up as the ref began a count.

The second round started with more trading by both boxers. Concepcion was more selective with his punches. He was landing the straight right hand often, and the uppercut up the middle. In the final minute they both stood their ground and were trading power shots at close range. There was no defense by either boxer. They were taking heavy blows. Marquez was taking more damage and almost went down for a second time as Concepcion started doubling up on the combinations.

At the start of the third, Marquez scored another quick knockdown on Concepcion. They continued to trade punches, shot for shot, as a packed house was standing on their feet. Concepcion got rocked again in the final minute of the round with a heavy combination of punches. This time Marquez was pressing the action and landing huge punches on the champion. Concepcion was somehow able to stay off the canvas and even traded punches in return.

Concepcion came out pressing in the fourth. Marquez was more confident in his ability to hurt the champion and stood his ground to trade punches instead of running from the exchanges. Marquez was rocking Concepcion with punches from both hands. The champion's face began to swell up.

A loud "Nica" chant began in the fifth round. The crowd was trying to lift the champion. Marquez was getting the better of the champion during their exchanges and his punches were doing more damage in the ring. 

Concepcion could not switch up his plan of attack. He only knows how to fight, by coming forward and trading big punches. Marquez was staying on his toes and catching Concepcion with counters coming inside. In the final minute he started attacking Concepcion with counters, but then the champion started landing big straight punches and then Marquez came back to hurt the champion with combinations.

The action slowed down in the seventh round for the first two minutes. They started trading again when the final minute of the round hit. Marquez was still landing better and picking off the champion.

The eight round was the slowest in the fight. They again waited until the final minute to start trading. Concpecion tried to jump on Marquez, who kept his distance and did well to pick his punches.
