Before you click on the video below – be warned, it is not for the squeamish!
Paraguayan defender Marcos Caceres suffered a serious arm injury during Newell’s Old Boys 1-0 win at Boca Juniors on Sunday.
Ten minutes before half-time, Caceres tussled with a Boca forward and fell to the ground.
To cushion the fall, Caceres put his arm down first and it more or less snapped.
On the final shot on the video below, you can hear the commentators wince with pain as it becomes clear what has happened.
Get well soon Marcos Caceres!
