Leeds United defender Liam Cooper was handed the shirt number no player at his club is permitted to wear, during his first international fixture.
Cooper was called up by Scotland for last night's friendly with Denmark, and was given the number 17 shirt.
No player at his club side has worn the number for the last two seasons, because club owner Massimo Cellino deems it bad luck.
The number did not prove especially lucky for Cooper either, who was an unused substitute for Scotland in their 1-0 victory.
Leeds recently titled their 17th home matchday programme of the season as issue number 16b upon instruction from Cellino - although still went on to lose that fixture to Nottingham Forest.
The Guardian reported in July 2014 that one of the reasons Cellino decided not to offer goalkeeper Paddy Kenny a new contract was because his birth date was May 17.
The same report says at Cellino's former club Cagliari, the Italian had the the number 17 taken out of stadium seating, and replaced with 16b.
Perhaps it was just as well Cooper did not get on and risk injury for Scotland, returning with a full bill of health to face Rotherham United this weekend in a must win derby for the Whites against Neil Warnock's side.
