Hugh Watson was signed by Celtic from Trabboch Thistle in May 1901.

His debut was a 3-0 Glasgow Cup victory at home to Clyde on September 14th. Originally signed as a half-back but was used by the Bhoys predominantly at right-back.

He was not the most subtle or refined of players but his all action approach to games meant he was a cult favourite among some fans. A leg break against Airdrie in January 1904 signalled the beginning of the end of his Celtic career as it was to be an injury from which he never really fully recovered from. Certainly eye witnesses at the time say Hugh was not the same player he had been.

He left Celtic – after 58 appearances and one goal - for Kilmarnock in October 1905 and would later join Belfast Celtic.
