After BJ Penn’s loss to Nick Diaz in October left the former UFC lightweight and welterweight champion with a recent record of 1-3-1 he declared that his fighting days may now be over.

In interviews towards the end of the year Penn still seemed to be sticking to the idea of at the very least taking an extended break, but the New Year appears to have brought about a new attitude from the Hawaiian if his latest Twitter message is anything to go by.

“@nickdiaz209 Look how much bigger you are in this pic..I thought you were gonna scrap from the beginning homie? What was that coward fence holding strategy to tire out the smaller man? Street fighter my ass! I made you fight like glass jaw @jonfitchdotnet poser! I’ll be ready for that weak bs next time we fight!”

When this message first appeared on Twitter yesterday many, including myself, believed it must be a hoax as it came completely out-of-the-blue, but later in the day Pedro Carrasco, the manager of Penn’s popular website confirmed that it did indeed come from the man himself.

“There is a reason why he posted it,” Carrasco stated in a post on the UG forum. “He is fired up because now that the holidays are over and a lot of his post-fight distractions are behind him he has nothing to do but think about things and he is not happy with the way he performed in his last several fights.”

He was also able to confirm that the message was an indication that Penn will fight in 2012.

“As it sits right now, he is back,” Carrasco said. “That killer mentality and fire is back and it’s been brewing for a while now and today’s tweet is a result of it just boiling over!

Personally I’m glad to see him back as he is still a force to be reckoned with and there’s plenty of interesting fights out there for him.

At the same time it would be wise to take the “killer mentality” hyperbole with a pinch of salt as we’ve heard this all before. Personally I’d rather he didn’t choose to get fired up about getting rematches with the likes of Diaz and Fitch and instead focused on a return to the lightweight division as he’s only going to continue to face bigger guys at welterweight and carrying the extra weight emphasizes his cardio deficencies.
