Quite frankly, I never trust anything that is said by Andy or his team for public or fan consumption. One frequently comes across statements that were cleary disingenuous in the light of later knowledge whether they concern his game, his coaches, his medical condition, or even his romantic life. Its all PR.
One can only go by what one sees and in the photo I saw he was clearly in pain in the right shoulder. We'll just have to wait to see how he looks on grass to know how serious it was.
