The unbeaten fighter spoiled the return of The Ultimate Fighter 18 finalist Davey Grant at UFC Hamburg on Sunday with a slick triangle choke submission that left Grant limp at the :59 mark of round one.
Bermudez hurt Grant with a right hand then immediately dove in to start working for his signature submission. Though Grant was defending intelligently at first, just seconds later he was clearly rendered unconscious and referee Tomasz Bendy was right on top of the action to wave off the bout.
With the win, Bermudez improved to 13-0 as a professional and 2-0 in the UFC, while Grant falls to 10-4 in his first fight since October 2016.
