Roma defender Federico Balzaretti has revealed that he might be forced to retire because of a persistent pelvic problem.
The Italy international has been out of action since November of last year and the 32-year-old now fears that his top-flight career is over.
"I wanted to hold this press conference to give you the latest on my injury and explain what I'm going through," Balzaretti told reporters on Tuesday.
"The issue came up around 10 months ago - I felt pain in my pelvis after the Torino game. As I'd never experienced anything like that, I just thought the pain would pass and I played the following game against Sassuolo.
"At the end of the match I had to stop and we noticed the injury to my pelvis.
"We tried an operation in the United States but it didn't produce great results. Then we tried a number of other things in Germany.
"This injury prevents me from doing even the most basic things on the field - every time I kick the ball it flares up.
"I want to be honest with the fans, just as I have been with my team-mates - sadly I still have months of rehab ahead of me.
"Sadly, this pain might end my career, but I want to say that I'll do everything I can to get back out there. I still feel like a footballer and I will try to get over this injury.
"I feel bad for my team-mates, I feel guilty and I would like to be able to experience the highs and lows with them."
Balzaretti, who has been capped 15 times by his country, joined Roma from Palermo in the summer of 2012 for a reported €4.5 million.
