Ron signed for Darlington in the summer of 1955 from Newcastle United and established himself as the rock at the heart of Darlington's defence for the next ten years, going on to make the most appearances for the club.

A run of 131 consecutive games from his debut was only halted when he was unable to reach Workington in February 1957 because of severe snowfalls. He broke a leg in the third game of the club's first season in the new Fourth Division in August 1958 and missed the rest of that campaign, but returned to miss only a handful of games during the first half of the Sixties.

Ron was a member of the 1966 promotion winning squad and played in most of our matches in Division Three in 1966/7, making his final appearance (and 439th in the Football League) in April 1967 against Bristol Rovers at Feethams. However having turned in a club record 490 appearances, Greener, more affectionately known as 'The Man Mountain' during his twelve years at Feethams, slipped out the back door almost unnoticed when he was given a free transfer by manager Jimmy Greenhalgh back in 1967.

It was a sad end to an otherwise distinguished career for the Easington-born player who not only contributed to the club's success a year before his exit but also played his part in some memorable cup upsets. Greener was at the heart of the Quakers defence which humbled First Division giants Chelsea in an FA Cup replay in 1958.
