You may remember Leon McKenzie from his days playing for Norwich City in the Premier League.
After dropping through the divisions towards the end of the career, the striker swapped football for boxing in 2013, winning his first professional bout in the second round.
On Saturday night, McKenzie made his TV debut on Sky Sports against Kelvin Young on the undercard of George Groves' fight with Andrea Di Luisa.
And the 37-year-old took just 43 seconds to win the super-middleweight title final eliminator with a powerful left hook.

We're now trying to think of who the next footballer-turned-boxer might be - Diego Costa, perhaps?
