That pic is Photo shopped or the arrow is high and is lodged in the muscle of the back strap. If it was to hit a lung that arrow would be moving alot and slice up more and more of the lung with every step the deer took. Also if you want to say it is the shoulder, then the shaft would still be in the lungmoving with every step and prevent a clot from forming.That is either a missed lung and somehow lodged above or photo shopped. Any one who has shot and recovered a deer with an arrow that did not pass through knows how much damage they do as they run and walk. Missed lung or photo shopped, only two possibilities!
