Christian Ribeiro: Knee injury forces Oxford United defender to retire
Oxford United defender Christian Ribeiro has been forced to retire due to a knee injury.
The 27-year-old former Bristol City trainee has been told by specialists if he continues playing it may affect his ability to walk later in life.
Ribeiro joined Oxford in June 2016 after being released by Exeter City.
"He's very sad, having worked very hard as a footballer to overcome these injuries," Oxford United manager Pep Clotet told BBC Radio Oxford.
Ribeiro made just 17 appearances for Oxford United during his time at the club, last appearing in the 4-3 Football League Trophy defeat by MK Dons on 7 November.
He made 188 appearances in a career that also took him to Scunthorpe, Carlisle and Colchester having made his Bristol City debut in August 2008.
"The fact he now has to put an end to his career based on a medical recommendation, it just shows how sometimes life is ruthless," Clotet added.
"One thing's for sure, he'll succeed in whatever he chooses to do in life. The amount of work he puts in made him earn everything that he has."
