UFC President Dana White made the announcement on twitter:
Alright Toronto!!! Dec 10th UFC 140 tix go on sale next weekend and ur main event is Bones Jones vs Machida!!!
This ends Dana’s dilemma of finding a health opponent for Lyoto Machida, its Bones Jones. Rashad Evans will have to wait for that title shot, he just had surgery to remove pins from his hand and its seems like Bones is now preoccupied with a Dragon.
