Those who tuned in to Channel 4's SAS: Who Dares Wins on Sunday night were left in shock after watching a male contestant brutally take down one of his female competitors, forcing her to leave the competition.
It all went down after chief instructor Rudy Reyes decided to pit the men and women up against each other in a game of 'murder ball'.
However, it wasn't long before a medical team rushed onto the scene when one tackle went very wrong. Watch here:

To play 'murder ball', competitors were placed in the middle of the Jordanian desert, and told to fight the opposing team for possession of a tyre.
Insisting that every contestant would be treated equally, organisers decided to put the women against the men.
It was all fun and games until contestant Jamie made a lunge for his competitor Pahrnia, to try and snatch the tyre from her grasp.
However, after being knocked down into the sand, Pahrnia stayed down, and was quickly swarmed by a team of paramedics.
Not long after, Pahrnia was declared physically unable to continue with the competition.
Speaking to her as she recovered, Rudy explained: "A brain and nervous system injury, or the possibility of one, can be fatal and we have more violence ahead on this course. Do you understand?"
Shocked by what they had just witnessed, viewers took to Twitter to discuss the gruesome clash.
"Noooo! Medically withdrawn!" tweeted one gutted viewer. "You can leave with pride, though, Pahrnia! You didn't voluntarily withdraw yourself! #SASWhoDaresWins".
A second wrote: "That’s heartbreaking for Pahrnia. "
A third irritated viewer complained: "‘Murderball’ is a ridiculous game to make the recruits play. A man spears a woman full force on a hill and now she has to withdraw… talk about unfair?! "
And a fourth added: "Gutted for Parnhia #17 she was an amazing recruit, she leaves with her head held high and the respect of the DS #SASWhoDaresWins".
SAS: Who Dares Wins continues on Sunday, 1st May at 9pm on Channel 4.
