A heartbroken family said they have been left with a hole in their lives "that will never be filled" after the sudden death of a "wonderful and loving son, brother and uncle".
Emergency services attended the scene and Mr Nicholas was taken to hospital but the 43-year-old could not be saved and later died of his injuries.
'A legend and absolute gentleman'
In an emotional tribute, his family said: “We are all heartbroken beyond words by the shocking and unacceptable loss of Andrew, known to all as Bandy.
"He was an amazing, wonderful, and loving son, brother, and uncle to his three nieces who adored him. He was a well-known and respected sportsman through semi-professional football and with his big passion, golf.“His passing has devastated the local golf community and his golf club where he was a key member, champion, and friend to so many. He was heavily involved with the club and ran charity and support events through Covid to support the NHS.
"The club members describe him as a legend and absolute gentleman. The hole that has been left in the lives of so many is one that will never be filled, and the pain caused will be with us for the rest of our lives.
"His loss will never be forgotten. The kind words of love and support we as a family have received has been incredible."
