Middleweight contender Marco Antonio Rubio (59-7-1, 51KOs) has had nearly 70 fights in a career that began in 2000. The boxer seems like he's been around forever, but he's only 34-years-old.

Last month he face feared puncher Gennady Golvkin for the WBA/IBO/WBC-interm titles and saw himself get knocked out in two rounds.

Now the boxer is considering the strong possibility of retirement, unless some very tempting comes along to drag him back into the ring.

"I'm not a 100% sure what I want. I'm enjoying my family, going to my gym and teaching young people. What I can say is that the only way [I'll fight again] is if we get offered something good, both economically and for a title, and if there is nothing then it's better to retire," Rubio told Fox Deportes.

"I was disappointed in a lot of things [with my last fight]. I felt that I stood up at nine, when the referee was counting. I stood up after taking some time to recover from the punch. I thought we were going to resume [fighting], but then he decided to stop the fight. I'm not a fighter who screams like crazy.....he simply stopped the fight and there was no turning back from that."

"I are already 34-years-old and starting over is very difficult. A lot of young strong guys coming and there is no money [in fighting them]. If there is something that suits us we will follow and if we do not get anything then I'll withdraw. I've had a nice career. I've been presented with great opportunities and thank God I fulfilled my desire to be WBC world champion. I met many people, many friends, many famous boxers. I've fought on large events, on two occasions when Oscar de la Hoya [was on the show]. I've fought in Ukraine, the United States, Canada...it has been awesome. "

"The boxing world is very ungrateful. You win and everyone is there with you, you lose and you get kicked [to the curb]. I have met many very good fighters and nobody remembers them. I am logical, I know that in a few years no one will remember me, but for me the most important thing is my family and my welfare."
