Barcelona skipper Carles Puyol admits he's feared for his career over his injury problems.

Puyol is recovering from a serious elbow injury.

"Injuries are the worst thing in football and I've had a few. I thought that one of them would force me to retire," Puyol stated in a story written for the blog 55dslstories.com.

"I worked day and night with my physio, Juanjo Brau, but couldn't recover. Some days it felt as though the discomfort had gone away but it was only temporary. It always returned.

"After four months I had to have surgery. The day after surgery we started working on my recovery, but I still felt the discomfort. That's when you start to think that maybe you'll never play again."
