Horrific moment Kell Brook's trainer downs a glass of SWEAT from the boxer's soaking t-shirt after a gruelling workout to prepare for his huge fight with Amir Khan

 Kell Brook's trainer has been filmed drinking the boxer's sweat during his gruelling preparations for his clash against Amir Khan, leaving boxing fans disgusted.

Brook is currently gearing up for fight night in Sheffield alongside Dominic Ingle, and a video has surfaced showing the two inside the ring after a brutal workout.

Taken from the Sky Sports documentary Behind the Ropes, the clip shows Ingle bizarrely drinking Brook's sweat before showing off the drained glass to the camera.

Ingle bizarrely agreed to sink the sweat after Brook rinsed a t-shirt out following a workout

'On the 19th you are going to get the blood and the tears from Khan, you can give me the sweat instead,' Ingle said. 'Am I alright to put this on Ebay?' In the clip, Brook is seen dripping in sweat after another hardcore session as he prepares to face his bitter rival Khan in the ring for the first time.

The Sheffield-born fighter showed off just how hard he'd work by squeezing his sweat-soaked t-shirt into the glass, filling it substantially. He then dared his pumped-up trainer to 'down it'.

Bizarrely, his long-serving coach duly agreed, holding the glass up to the light to show viewers another angle of the sweat before gulping it all down.

Despite daring his trainer to perform the stomach-churning act, Brook appeared surprised that Ingle had gone ahead with it in front of the Sky Sports cameras. 

Social media users expressed their disbelief with the moment, with YouTuber-turned-boxer KSI saying 'This ain't it' with a laughing emoji.

'What have I just seen?' another wrote, accompanied by four sick emojis.

A third jokingly posted: 'Behold... Dominsick Ingle'. 

'Not even funny,' a fourth said. 'That is disgusting!'
