Sadly, I have a bit of personal experience from which to offer my insights. In a city league game (in which I played center with my full 5'11” since we only had 5 players) I got my pinkie finger dislocated (second knuckle). As I stared down at my bone riding up over the next bone up, I mustered the wherewithal to try to pull it down into place (remember only 5 players, and no center). Unfortunately my first effort resulted in a slip and, lacking the bravery to try again, I turned to my best friend on the team and asked him to try.
