Mauricio Rua and Dana WhiteOn Thursday afternoon news broke that Quinton “Rampage” Jackson had passed on a title bout against Lyoto Machida to take on Rashad Evans later this year, likely at the UFC’s year-end show in late-December. Now, according to rumors, Machida could meet Mauricio “Shogun” Rua in September in the main event of UFC 103.

Rua was in the UFC offices earlier this week and may have been negotiating to fight Machida at the fall event, which is now rumored to take place in Texas and currently lacks a main event.
