Carlos Tevez somehow didn't even receive a card for this dreadful challenge which broke the leg of Argentinos Juniors midfielder Ezequiel Ham.
Tevez was already on a yellow card at the time but regardless, it most certainly should have been a straight red. For what it's worth Boca Juniors went on to win the game 3-1, with the former Juventus striker having earlier scored a brace.
Be warned, the video of the tackle is fairly gruesome.
