Ross Pearson will have surgery in two weeks.

The Ultimate Fighter (TUF) Season 9 winner not only suffered defeat in his last bout with fellow reality show graduate Cole Miller, he also tore the cartilage in his knee during the 155-pound scrap.

"The Real Deal" is expected to be out of action until at least Spring 2011. While the Brit tore his knee during the fight, Pearson tells Fighter's Only it's no excuse for losing to "Magrinho."

"I think it tore when he pulled guard on me. After that I was really heavy-footed and I lost my movement. I am not using that as an excuse though, Cole Miller beat me fair and square. I didn’t want to mention it at all but now I am having an operation I suppose it would come out sooner or later."

Before being defeated for the first time in his UFC career back on Sept. 15, Pearson was a perfect 3-0 inside the Octagon, defeating Aaron Riley at UFC 105 and Denis Siver at UFC Fight Night 21 after his debut win over Andre Winner at TUF 9 finale in June 2009.
