Kellen Fisher joined Norwich City in the summer of 2023, making the switch from Vanarama National League side Bromley.

The full-back progressed through Bromley's academy before making his senior debut in the FA Trophy against Dover Athletic.

After gaining further first-team experience on loan at Welling United, Fisher returned to Hayes Lane and established himself in the Bromley side, making 27 National League appearances during the 2022/23 season, including both of the club's National League play-off fixtures.

The then 19-year-old completed his move to Carrow Road in June 2023 and quickly developed into a regular member of the Canaries' first-team squad.

Fisher reached a significant milestone in April 2026, making his 100th Norwich City appearance in the Championship fixture against Derby County.
