Grant Hanley will miss the bulk of Scotland’s Euro 2024 qualification campaign after rupturing an Achilles tendon.
The Norwich centre-half started in the heart of Scotland’s defence in the opening two qualifying wins over Cyprus and Spain.
But he has been consigned to a lengthy lay-off after suffering an injury against former club Blackburn on Good Friday.
Hanley will face a battle to get back for the remainder of the group games, which culminate with matches against Georgia and Norway in mid-November.
“Grant has ruptured his Achilles tendon and is having an operation this week. He will be out for months,” Norwich manager David Wagner said.
Scotland also face Norway and Georgia in June in their next two qualifiers.
