Arsenal defender Kieran Tierney will miss out on a historic occasion for Scotland at Euro 2020 this afternoon.
Featuring in their first major international tournament since the 1998 World Cup in France, the Tartan Army kick-off their Group D charge against the Czech Republic at Hampden Park.
Of course, it's an opening clash which takes that has significance for England, too, on the back of their 1-0 win over Croatia in the same group yesterday afternoon.
A key part of the Scotland squad, Tierney presumably misses out against the Czechs due to injury - with the former Celtic man not even included on the substitutes bench.
It comes as a massive blow to the Scots ahead of their return to the biggest international stage.
Here is how a selection of Arsenal supporters reacted to the news on social media.
@aaroncallo said: "Tierney isn't injury prone, but has a fear of injury. It's a mental thing he must overcome."
@southldngunner posted: "Was looking forward to watching Tierney today for Scotland. Has done well for AFC when playing as that third centre-half in a three."
@Stuart_Murphy added: "Tierney saving himself for next season's title challenge. What a guy."
How much will Scotland struggle without Tierney? Let us know in the comments section below.
@DUKETHAPRODUCER said: "Tierney is becoming injury prone. All this back-up LB talk needs to stop. We need a proper LB that can challenge Tierney for the number one spot."
@Emzyl23 posted: "Tierney was supposed to be out for the rest of the season, then he was back four weeks later, or so, and now he's out injured again. He should never have played for Arsenal after the injury against Liverpool."
@freshhx0 added: "Sell this Tierney guy asap, made out of glass."
