Forward Kenneth Aboh made his first appearance for Norwich City Under-18s in the 5-1 defeat to Arsenal on 31st October 2020. He came on as a 67th minute substitute for Joe Duffy.

Aboh was part of the Langley Schools team that won the Playstation Small Schools Trophy in May 2017 at Pride Park and the Norfolk Schools County Cup with teammates including Spencer Keller, George Sims and Alex Matos. Langley's Head of Football was Darren Eadie.

On 16th July 2021 it was confirmed he was awarded a scholarship deal with Norwich. He scored nine goals for the Under-18s in 2021/22. He signed his first professional contract with Norwich in December 2021.

Considered one of Norwich's hotest prospects, there were rumours of a League One loan in January 2024 but these did not materialise. It is concerned that Aboh might leave the club in the summer of 2023 on a free similar to Alex Matos who joined Chelsea.

His impressive form saw him included on the bench for Norwich's Championship clash with Cardiff on 17th February 2024. He made his professional debut on 9th March 2024 coming on as an 81st minute substitute for Ashley Barnes in the 5-0 defeat of Rotherham at Carrow Road. He didn't make any further appearances that season.

On 2nd July 2024 Ken signed a new contract keeping him at Carrow Road until 2027 with the club having an additional one year option. He was due to be out of contract and there was speculation that he would move on although City would have been entitled to compensation.

On 30th August 2024 he joined League One side Stevenage on loan from City with the Hertfordshire side fighting off competition from MK Dons and Notts County for his signature. He made his debut on 31st August coming on as an 84th minute substitute in a 1-0 home defeat to Lincoln.
