Argentina – Just minutes after uploading a photo of himself while walking his dog, Argentine soccer sensation Lionel Messi noticed a sharp pain in both of his knees. “I’m not sure what happened… I woke up, got dressed, and went out for a walk. Suddenly, I felt a strange knee pain in both legs,” a mystified Messi told reporters. Messi has been largely injury-free throughout his career, though initial medical reports suggest that the Adidas-sponsored athlete may need to undergo surgery for what is likely a torn ACL in both legs. When asked how this could happen so suddenly, Messi was unsure, but immediately went home to change.
