Results from an MRI scan of Cardinals catcher Yadier Molinas right knee revealed a super gross mess of blood, cartilage, and tendons inside the joint, concerned radiologists confirmed Thursday. Yadiers knee appears to be full of all this nasty, slimy stuff that totally makes you want to puke, said Saint Louis Universitys Dr. Joseph Farber, adding that there are a bunch of nasty worm-like things everywhere in the completely disgusting knee. Its all wet and greasy, too, almost like ground beef or brains. Ugh, I dont even want to look at it, let alone touch it. Farber added that Molina should avoid putting any weight on the knee, warning that doing so would probably cause it to fall apart or explode or something.
