Training sessions can get pretty intense, especially when players have to battle the heat, exhaustion and a list of other factors. Occasionally things can boil over, too, and players can come to blows.

In fact, the dust-up was a ruse to prank manager John Herdman for his birthday, which was July 19. Not exactly your run-of-the-mill birthday surprise, but the team appears to have pulled it off masterfully.

With Rio coming up, Herdman can hang his hat on his team's ability to choreograph a quality set piece.
