Roy Nelson showed plenty of heart and a remarkable chin against Junior Dos Santos at UFC 117, but ultimately he was well beaten in the bout and missed out on a heavyweight title shot.

Late last week Nelson revealed he would now be taking time off to have knee surgery, and he was checked into hospital yesterday for the procedure that should keep him out of action for several months.

Before he went under the knife though Nelson found time to give his thoughts on a couple of his fellow UFC heavyweight’s via his twitter account.

First up was Nelson’s reaction to the news that Shane Carwin had been mentioned during a recent trial as having received steroids back in 2006.

“Just woke up and was reading the mma news websites and only one had real news ufc champ shane carwin steroids court case.

I am surprised that athletes in mma do steroids ;( that explains body types).

Let see if real news sources investigate the steroid claims, mmajunkie, mmaweekly, sherdog, espn, etc I like good news.” – Roy Nelson

Carwin hasn’t yet responded to the allegations about his alleged steroid use, though he is expected to do so later this week, but he did find time to retort to Nelson’s dig at him.

“I love Roy Nelson trying to elevate his status by talking smacks. Hopefully he is doing so on a treadmil. Some have rolls he has a bakery.” – Shane Carwin

UFC executives had hinted prior to UFC 117’s Dos Santos Vs Nelson fight may well be Carwin’s next opponent, but with Nelson out injured that’s now unlikely to be the case.  If their war of words escalates though then it may not be long before the fight does eventually become a reality.

For the time being it appears that Nelson has another opponent in mind however.

“I just read big nog is out, so after I get knee surgery, we both can give the fans a show of heart, and great jits, and the next title shot after that.”

Like Nelson, Nogueira has just announced that he too is heading for surgery, in his case for his knee and his hips.  So it’s certainly not beyond the realms of possibility that when they both get back to full fitness they could face in the octagon, though I don’t expect that such a fight would be enough to propel either man to a title shot as things stand.
