JORDAN King needed only 50 seconds to record the fifth win of his professional career when he stopped Iain Jackson at the Metro Radio Arena.
The Hetton light-heavy had been due to face Jamie Ambler at the major Newcastle event, only for the Welshman to pull out this week.
Jackson stepped in as a late sub and probably wished he had stayed in Brighton.
He was game from the opening bell but was too open and when King landed a stunning right, down went the veteran operator.
Referee Andrew Wright reached five before ending the bout which had been scheduled for four rounds.
After prompt medical attention, Jackson recovered relatively quickly and left the ring unaided.
But it was a dynamic show from the local prospect who was cheered on by 200 fans.
