It’s one of the biggest topics for polemic in the sport of MMA: do you allow knees to the head of a grounded opponent and what should be rightfully deemed as a ‘grounded opponent’?
Recently, we had an interesting situation when a main card opener for UFC 297 between Arnold Allen and Movsar Evloev produced one sequence that confused a lot of the fanbase. Marc Goddard had paused the bout in 3rd round, when the Englishman kneed Evloev in the head multiple times, while the latter was touching the ground in order to place himself as a grounded individual, unable to get kneed to the head.
