A little research and it seems that the boxer Ricky Hatton has been diagnosed with Thompson's MC.

I'm not a boxing fan so I missed this one but it's interesting that Google does not return links to any major British newspapers in relation to this story. Indeed, most of the medical concerns with Hatton appear to be with boxers developing Parkinson's Disease!

Also, all the retirement talk seems to concern the manner of his defeat by Manny Pacquiao back in May of this year.

This story has me curious, I'm going to dig some more!

Glad to see this has sparked interest. Please keep me posted on what people find out.

Have a blessed holiday season.

Having had a bit of a search, it looks more like some clever person likened Ricky Hatton's falling in his last fight to the fainting goats.
They made up a story on boxing forums and posted a YouTube video showing the similarity.

I could be wrong, but it has the hallmarks of a wind-up for the fans of Ricky Hatton.
