With both competitors taking verbal shots at one another via Twitter, Lyoto Machida's ongoing feud with Chael Sonnen could culminate into a potential bout in the near future.
The former UFC light heavyweight champion recently underwent successful surgery to repair an elbow injury and posted the results on his Twitter account. Machida is coming off a loss to Jon Jones at UFC 140, where the Brazilian was submitted in the second round.
"The Dragon" also called out Sonnen in response to the UFC middleweight contender's comments regarding Machida's practice of urine therapy.
"Chael Sonnen, I just got out of an surgery but I can give you your Christmas gift inside the octagon with only one arm. Just take the fight," Machida wrote.
Sonnen responded to Machida's challenge a few hours later, but he initially declined the option of facing him.
Sonnen is already expected to meet Mark Munoz later this month on UFC on FOX 2; the winner is scheduled to face Anderson Silva in a middleweight title bout later this year.
If Sonnen is unsuccessful in beating Munoz, there is the possibility of witnessing a matchup between the Oregon native and Machida at 185 pounds. Machida has expressed interest in moving down to the middleweight division if he is unable to recapture the UFC light heavyweight championship.
