Schleib, 12-2 prior to this fight, was in desperate need of a win coming off the back of two knockout defeats and he bounced back in spectacular fashion.

In round five of the fight, the 30-year-old Schleib found the finish, as he caught his opponent with a thunderous left hook.

Ram Anuj was immediately put to sleep, as his legs buckled and he collapsed down to the canvas.

But, on his way down he was caught by the ropes and he slumped against them unconscious, as Schleib was awarded the victory.
