Former Derry City player Mark Farren has passed away, aged 33, after a battle with cancer.
Farren, the Candystripes all-time leading scorer, had travelled to a specialist clinic in Tijuana, northern Mexico last summer for treatment on a grade four brain tumour.
However, the Donegal native passed away this morning, with tributes flooding in for the talented striker.
Farren played for Finn Harps, Monaghan United and Glenavon but it was at Derry he truly shone, scoring 114 times in a prolific spell with the club.
He was named the League of Ireland player of the year in 2005, and had battled illness for the last six years.
FAI chief executive John Delaney said: "Mark’s sad passing is a devastating blow to everybody in Irish football. He was not only a tremendous talent, but a real gentleman, who was widely respected in the League and very popular with his team-mates throughout his years in the game.
"I would like to pass on my deepest condolences to Mark’s family."
