Ryback recently posted this picture of his swollen knee on Instagram- caused by a staph infection - and added this comment to the image: "And this is the best it has looked and felt. Wouldn't wish this upon anyone, but it will be overcome. Staying upbeat and positive even in frustration."
At this point it sure doesn't look like Ryback will be able to compete to defend his Intercontinental Champion belt in a 30-day window and many are speculating that the WWE will go ahead and vacate said title from him - a title he has only held for about a month.
This situation is kind of deja vu given that Ryback won the title when former champion Daniel Bryan was injured a little over a month into his reign as Intercontinental Champion and had his belt vacated.
