THE BBC's big budget new reality show Survivor was rocked by a gruesome injury tonight.
A brutal challenge was brought to an untimely end as two contestants clashed heads while facing off for their respective camps.
One by one, members of each camp battled it out in Sumo at Sea, a head-to-head game on a platform in the sea.
The contestants, each armed with a heavy bag, went to war to see who could forcibly knock their opponent into the water.
Every winner received a point, with the first tribe to rack up five winning a reward.
Survivor start date revealed as BBC reboots show - and it's just DAYS away
Host Joel Dommett quipped it was an aggressive pillow fight.
But it proved much more testing than he could have imagined after a sickening clash of heads.
Christopher and Rachel's bout ended early when they collided.
Joel immediately called for the medic while the two camps watched on in sock.
Pained Christopher clutched his mouth while Rachel lay prone on the platform.
When she was pulled up, blood oozed from a nasty gash on her head.
Fortunately both parties made a full recovery and were soon their usual selves back on dry land.
Christopher looks set to be in the wars once again as a trailer for next week's show saw medics rush to his aid as he collapsed to the floor in another tough challenge.
