Be careful how you read the title of this post. Roger Huerta did not resign from the UFC, but he did re-sign a contract with the UFC. It was very public that Huerta was in a small feud with the UFC over a contract. He wanted big bucks, I mean six figures per fight big. He was very public in his criticism of the UFC. However, it looks like that is resolved as MMAWeekly is reporting that Huerta has signed a new five fight deal with the UFC and may return to action in March.
Huerta is a legit top ten lightweight, but I do not know if he can crack the top 5. However, it is good to see him stick around.
