Photos: Pacquiao, Pitt & more sports drama

Losing hurts. Double, if it comes by way of a thunderous punch to the head.

Of course, Pacquiao wasn't the only person to experience the pain of losing this weekend. So, Playbook and the aptly named Tumblr "The Agony of Defeat" bring you a collection of dramatic recent sports photos, all showing the other side of a sports outcome -- the beaten.
