Derry star Paddy Bradley has said he is unsure if he has the desire to return to football following another cruciate ligagment injury.
Bradley suffered the injury last week in club training and will have an operation at the end of October.
He sustained a similar injury in April 2011.
Bradley told the Irish Independent: "I know it's possible for me to return, even for next year's Ulster championship, but only if I do everything right. Whether I have the drive for that, I just can't say right now.
"I did everything right with my rehabilitation the last time. It can turn your life upside down.
"I was in the gym most mornings before I went to school.
"But now I have two children and I have changed teaching jobs, which has given me more responsibility. I can't really say if I can give my recovery everything required to be back to where I was," he said.
