As a player he was a defender or midfielder starting his career at Exeter City before a controversial transfer to local rivals Plymouth Argyle. For this reason, the Plymouth fans took time to accept Marker but his whole hearted performances in a green shirt soon made him a fans' favourite. Marker was awarded the clubs Player of the Year award in 1990.
His performances for Argyle also caught the eye of then Blackburn Rovers manager Kenny Dalglish who paid £500,000 to bring Marker to Ewood Park, with both Keith Hill and Craig Skinner moving in the opposite direction. Marker's first team involvement at Blackburn was limited as he was largely used as backup for regular centre-backs Colin Hendry and Henning Berg, or holding midfielder David Batty. He played no games in Blackburn's Premiership 1994/5 title-winning season.
He moved on to Sheffield United in 1997 and made regular appearances over two seasons. However, by this time hip and back injuries were beginning to take their toll and Marker returned to Plymouth Argyle for a short loan period, before spells at Cheltenham Town and Tiverton Town where injuries eventually forced him into premature retirement.
In 2011, eleven years after his retirement, two hip replacements, and at the age of 46, Marker made a single appearance for Ivybridge Town, coming on as a late substitute in a South West Peninsula League match at home to Dartmouth. He was cautioned for a late tackle within two minutes of his introduction.
After retiring from the professional game Marker was involved with Plymouth amateur and youth club Tamarside FC from 2003 to 2009. He joined the club in 2003 to initially help coach his son's team, later getting involved in the club's senior team and was appointed club Chairman in 2006. He combined the role of Reserve Team manager and Youth Manager until leaving the club at the end of the 2008-09 season.
In June 2013 Marker was appointed First Team Manager after the resignation of Graeme Kirkup.
