Former Coventry City striker Leon McKenzie won his ninth professional fight with a first round knockout.
McKenzie took on IBO champion Kelvin Young at the Copperbox Arena, London in a title eliminator and had him on the canvas with just forty three seconds gone.
Refereee Terry O'Connor immediately stopped the fight following a flurry of punches from McKenzie including a big left hander on the chin.
McKenzie said: "I hope I convinced people. Kelvin conducted himself professionally but now we are rocking and rolling.
There is a few things we can do and I will let my manager decide that."
