Flood was one of the founding members of St Sidwell’s United, the club that became Exeter City in 1904, and appeared in the first game for which details of the complete line-up have survived.

Prior to the 1901/02 season he is known to have played for St James, another Exeter club. He then joined the new St Sidwell’s United club that had been formed largely by a group of 16- and 17-year olds who had attended St Sidwell’s school and lived close to the current St James’ Park.

Playing at right-back, he is first recorded as a member of the side that faced St David’s on 12 October 1901 although it is entirely possible that he had played in previous games for which records no longer survive.

Thereafter he appeared in all of the 1901/02 fixtures for which records remain although there is no mention of him in subsequent seasons.

The 1901 census includes an entry for a Harry Flood (18), a painter with a coachbuilder, living in Parr Street, Exeter.
