Khan, who was making his 15th competitive appearance, was selected to fight the experienced Lewicki, from the Sheffield City Boxing Club.
Lewicki was a dominant force in the 75kg category and Khan was making his debut at that weight having previously boxed at 64 and 69kg and the move up was a huge step in terms of power and physical appearance.
Lewicki is national champion and also the English belt holder at 75KG and the Sheffield man has boxed at a superior level during his 72 fights and was a strong favourite to win.
In an action packed first round, both boxers exchanged combinations.
It proved the most exciting round of any of the championship fights taking place but Lewicki appeared to get the better of the exchanges towards the end of the round and did enough to win it.
Khan put Lewicki under pressure at the start of the second round, forcing him on to the back foot with nicely placed combinations of uppercuts and hooks drawing blood from his opponent to take the round.
With the fight level going into the final round, both men knew a place in the Yorkshire final was up for grabs.
A loud roar from the crowd greeted the boxers at the start of the third, knowing they had been thoroughly entertained.
It was very evident that both fighters were determined to secure victory and for the entire three minutes, they exchanged a barrage of blows.
Khan was producing the cleaner combinations while absorbing the majority of Lewicki’s shots.
Khan rallied and forced Lewicki onto the back foot and ultimately on the ropes with some devastating body shots.
Khan pressed for the entire round with both men having nothing left in the tank, they were relieved to hear the final bell and received a deserved standing ovation from the audience.
Khan was declared the winner by split decision, which sees the Dewsbury man through to the regional final, where he will face Shakeel Thompson from the Manor Boxing Academy.
