James McClean admits his career is in jeopardy due to a long-standing hip injury and will explore the possibility of surgery to fix the problem.

The 37-year-old returned to Derry City this season, but says the Brandywell’s astroturf surface has acerbated the issue and received medical advice that he “has no business being on a football pitch”.

The Candystripes’ surface is in the process of being replaced with the grass surface at Derry GAA’s Celtic Park set to host at least five games until it is ready, beginning with Friday’s Premier Division clash against Shamrock Rovers [20:00 BST].

McClean, who was sent off for two yellows in the 2-2 draw against Dundalk on 10 April, is theoretically free to play, but is focused on what could be a “last chance for me to hopefully get a surgery”.

“I was told by a specialist 10 days ago that my body currently ‘has no business being on a football pitch’ due to the severity of the damage to my hip,” he posted on social media.

“I respect his honesty and his expert opinion, but I have never been one to lay down without a fight.

“Tomorrow’s appointment is a last chance for me to hopefully get a surgery – if it’s even a possibility – one which will allow me to do what I have dreamt of doing, and that’s being able to contribute while in an acceptable physical state to do so. That is playing for a club I love in Derry City.”

The former Republic of Ireland international, who spent 15 years at English and Welsh clubs after first leaving the Brandywell in 2011, said he wanted to set the record straight about the “hell” he has gone through due the hip problem.

“For the past few years, I have been playing through difficulties with my hip and though I have managed and played through the pain, the impact of training and playing on astro has sped up the damage much faster than I ever anticipated,” he explained.

“The past six weeks have been hell – pain is something I have been able to get on with and play with throughout my career, but it is the restriction and not being able to move which is what I am struggling with physically obviously, but also mentally.”
