Defender Thomas Dunbar is one the few players to have the distinction of having played for both Celtic and Rangers.

The younger brother of Michael Dunbar he enjoyed two spells at Parkhead in the early seasons of the club. He initially signed for the Bhoys from Busby Cartvale in 1890 and his debut came at the Gers in a 2-1 league victory on May 2nd 1891.

He joined Rangers in November 1891 but returned to the Bhoys by July the following year. It should be noted though that at this time the Celtic and Rangers rivalry was of a much more friendly nature and that Rangers were still some years off of adopting their hardline 'No Catholic' sectarian signing policy.

As a Celt Tom was primarily a reserve but he was a very able and reliable deputy who was frequently called to stand in for the likes of Dan Doyle. He enjoyed a realitively long Celtic career and made 60 appearances and scored 4 goals before leaving in 1897.
