I hadn't heard anything about an injury to Crotta, but he mentioned yesterday on Twitter that he was having surgery at The Andrews Institute. He tweeted more today:
Long day! Took out some bone spurs and put a pretty massive screw in, pictures coming soon.
True to his word, he posted two X-rays and what is a very large spur that was removed from his elbow. I've never seen one before, but I can see why there would be discomfort.
Tough break for him. Not much has gone well after opening last season on the Opening Day roster. Hopefully he'll make a full recovery.
