Scotland face a major doubt over Kieran Tierney 's fitness with the Arsenal star reportedly requiring surgery on a knee injury.
Tierney missed the Gunners' shock 3-0 defeat away at Crystal Palace, one that allowed rivals Tottenham to keep their spot in the Champions League places ahead of them.
The Athletic report that the former Celtic full-back will now miss the remainder of the campaign and is a major doubt for Scotland's crucial World Cup playoff.
