Capped once by Wales in a 2015 World Cup warm-up match against Ireland, he was forced to undergo back surgery last year and has now had to accept that his professional career is over. He made his Ospreys debut at 18 and scored 23 tries in 81 appearances.
His last game was a regional derby against Cardiff Blues at the end of 2016. He underwent surgery in February, 2017, and was hoping to return to action this season, but after consultation with specialists he has made the decision to retire.
“It is extremely difficult thing to do, acknowledging and making the decision that you have to retire from the game, but it is absolutely the right thing for me to do,” said Walker.
“I’ve worked hard to try to get back to where I was pre-surgery but, unfortunately, I recognise that I am not going to be able to do so. I’m immensely proud of everything I’ve achieved on the rugby pitch, be that playing for Swansea, representing the Ospreys, or gaining my full Wales cap.
“Without the support of my mother, in particular, I wouldn’t have able to achieve anything like I have in my career.
There are so many fantastic memories that will live with me forever and the sport has allowed me to meet some fantastic people who are now firm friends.”
Capped at Wales Under 18 level, Walker helped Wales Under 20 beat New Zealand at the 2012 Junior World Championships and finish in third place. The Gorseinon RFC product graduated throughout the age-grade teams at the Ospreys, played for Swansea and helped the Ospreys win the PRO12 title in 2011/12.
“Everyone is saddened by this news. Eli is someone who came through the development system and was identified at a young age as having the potential to become a senior player for the region and for Wales,” said Andrew Millward, Ospreys Managing Director.
“He established a reputation as a quality finisher of the highest level and enjoyed many stand-out moments in an Ospreys shirt. His try in the unforgettable win over Toulouse at the Liberty Stadium summed up his ability.
“It is a real shame for Eli, and for the Ospreys, that injury has cut short his career before even reaching what should have been his prime. However, he should be proud of what he has done in the black shirt and how he has represented himself, his family and the region.”
