The former Luton Town and Portsmouth player confirmed his retirement on social media, bringing an end to a career that saw him win 37 caps for Wales and feature at both Euro 2020 and the 2022 World Cup.
“This is not something that I ever thought that I would be writing at the age of 28, but today I’ve officially retired from professional football,” Morrell said.
“After almost two years of rehab, trying to get my body back in to a place to train, play and compete in the professional game, I’ve had to admit the fact that I am no longer capable of this.
“It’s been an incredibly tough 21 months, full of promise, hope, tears and dark moments, but I’m at peace with the fact that I’ll never again be able to play.”
Morrell suffered knee cartilage damage in January 2024 while playing for Portsmouth and has not featured since.
Despite extensive rehabilitation, the midfielder said the injury ultimately forced his decision.
The Ipswich-born player, who began his career at Bristol City, made his international debut in 2019 and was a key figure in Wales’ recent major tournament campaigns.
His last appearance came as a substitute in the goalless friendly draw against South Korea in September 2023.
Morrell said the support of those closest to him had helped him through a difficult period.
“I can’t thank my close friends, family and most importantly my amazing wife enough, for the support that they’ve given me during this time,” he said.
“I firmly believe that I will come out of this period a more resilient, well-rounded person with a greater sense of perspective on what’s important in life.”
He has already moved into coaching, recently earning his UEFA A Licence through the Football Association of Wales’ coaching programme, and is a co-owner of Merthyr Town.
“Football is what I do and not who I am,” Morrell added.
“Being able to live out not just my dream, but the dream of millions of boys and girls around the world was never something that I took for granted.”
