Playing career A goal kicking fullback, Davidson played for the
City Rovers between 1915 and 1923 in the
Auckland Rugby League competition. Even as a young player his goal kicking became well known. In 1914 when he was still in the City 2nd Grade team he was reported thus: "this boy, Davidson, of City, is said to be a remarkable place kicker and half a dozen goals in one afternoon has been no uncommon achievement for him this season. He kicks them from all angles and all ranges, and many old players and officials have described him as easily the best goal kicker in Auckland". In 1922 he played for Auckland against the touring New South Wales team where Auckland lost 40 points to 25. He played against the same team days later for the Auckland Provincial team who also went down by 21 points to 20.
Coaching career In 1927 Davidson coached the Buller side in their match against Auckland. Buller were badly outmatched and lost heavily but still managed to score 33 points in the 60-33 result.{{cite news ==Administration career==
