He was released by City on 4th May 2018.
On 30th July 2018, he signed for Southern League side Tamworth.
Lambs boss Mike Fowler said “Owen’s a good signing for us. Last year he was Norwich City’s under-23s captain and I know their coach, Matt Gill, thought he’d get offered a professional deal. We have managed to take him on board and I’m delighted. Owen’s only 19 but he’s an intelligent player who has got great technical ability. He is someone who can defend smartly. He reads the game well and he’s a fantastic passer of the ball, which will be key for us.”
