Juan Manuel Lopez vs. Bernabe Concepcion: Round By Round

Gus Johnson and Al Bernstein are calling the action tonight as Showtime Championship Boxing is live in San Juan, Puerto Rico. We just saw a knockout for Nonito Donaire in the co-feature, and we're awaiting Juan Manuel Lopez and his battle with Bernabe Concepcion.

Over 80 percent of the people who voted in Showtime's poll think this fight will end with a KO. Both fighters have impressive knockout percentages, so that's very possible.

Bernstein thinks Lopez isn't quite up there with the all-time Puerto Rican greats because he doesn't have a career-defining win or rivalry yet. He gives Concepcion a chance to pull off the upset, but says he will have to fight at the highest level of his career to do so.

Concepcion comes to the ring first to the sounds of "We Will Rock You" by Queen. He is 28-3 with 15 KOs, and he's coming in off a win following a DQ loss to Steven Luevano last August.

Juanma makes his way to the ring with pink gloves and a pink robe. He's doing so to dedicate the bout to fighting breast cancer, and he is going to auction off his gloves after the bout to aid cancer research. Lopez is 28-0 with 25 KOs and has a date with Rafael Marquez later this year if he takes care of business tonight.

Jimmy Lennon Jr. does the introductions to get us ready for 12 rounds of boxing for Juanma's WBO featherweight title.

Round One

Both fighters look confident and relaxed. Concepcion is coming forward, but Juanma quickly knocks him back to the ropes with a left hand. Another left hand connects, and Concepcion is down early.

He beats the count but has about 90 seconds to survive.

Concepcion tries to weather the storm as Juanma attempts to pour on the left hands.

Lopez batters his way into the corner, but Concepcion digs in and lands a left hand of his own, and Juanma is down. Scintillating action in that first round!

Tylwalk: 10-10

Round Two

Concepcion comes out aggressively, but Lopez connects with a straight left and sends Concepcion down again. He's back up with over two minutes left in the round.

Crazy stuff so far.

Not much subtlety here with both men trying to land bombs. Now it settles down a bit, but neither guy is getting cheated when he swings.

Thumping right by Concepcion, but Juanma digs in and lands a combination that earns yet another knockdown. Concepcion tries to continue, but the ref is calling it.

It's a short but exciting main event.

Replays show that the first knockdown in Round Two came from a straight left following a pretty big right by Concepcion. Then, it was a right hand that got Concepcion wobbly before Juanma moved in and finished him off with a flurry from both hands.

The winner by TKO at 2:37 of Round Two... and still WBO featherweight titleholder... Juan Manuel "Juanma" Lopez.

Through his interpreter, Lopez tells Jim Gray that he got a little overconfident when he got tagged toward the end of Round One. He still felt strong though, and he was able to come back and get the KO in the second round.

Juanma is looking forward to fighting Rafael Marquez later this year, and he says the contracts are all good, and that the fight will be on Showtime.

Bernstein says that Lopez is exciting because he's talented and powerful, but has enough vulnerability to keep things interesting. He feels like Marquez will definitely land some punches against Juanma, but isn't sure if he'll be able to deal with Lopez's power.
