Having previously been at Dundee, Marcus Dailly had a single season with Exeter City for whom he made his only appearances in English football. He later became a teacher and published a novel. 

The younger brother of Christian Dailly (Dundee United, Derby County, Blackburn Rovers, West Ham United, Rangers, Charlton Athletic and Scotland), he had made three first-team appearances for Dundee prior to linking up with Exeter City in August 1996. Whilst with the Dens Park club, the twenty-year-old Marcus had also enjoyed a two-month spell on loan with Dundalk around the time the Louth club became League of Ireland champions. 

With Dundalk keen for Marcus to stay he eventually left Dundee to sign for Exeter City and made his debut for the Grecians against Scarborough on 24 August 1996. Never winning a regular berth in the team, and making no more than a dozen starts in all competitions, he left after one season at St James’ Park to return to Scotland to sign for Brechin City.

Marcus played 25 league games for the Glebe Park club ahead of appearing in Tayside junior football for Lochee United and Lochee Harp whilst studying English and psychology at Dundee University. He later worked as a journalist before moving to Dublin where he became a teacher, published a novel and remained in football as a youth coach with Malahide United. His sister Stefani Dailly became a broadcast journalist with STV in GIasgow.
