Fighter 'turns into zombie' after brutal KO punch

An Irish MMA fighter has somehow managed to stay on his feet despite appearing to be knocked out cold by a huge punch.

Steve Mutzu was taking on Jason Stevenson at Shamrock FC 305 recently when he was hit by a huge right hand just five seconds into the bout.

But instead of falling to the canvas straight away, Mutzu stayed on his feet despite appearing to be out cold.

He took a couple of groggy steps forward before Stevenson hit him with another blow, sending him crashing to the mat.

The referee inexplicably allowed Stevenson to land one more punch before calling the fight after just 10 seconds.

Mutzu’s ability to stay on his feet while out cold has resulted in some describing him as looking like a ‘zombie’.
