The Gunners have released their team news ahead of their final Europa League group stage fixture with Standard Liege. It details that the 22-year-old has suffered a dislocated right shoulder.
Tierney will undergo more assessments and investigations to determine how long he is out for.
A race for the play-offs?
Initial reports over the timescale of Tierney’s recovery do not sound good. It could leave him in a race against time to be fit for Scotland’s crucial Euro play-off matches in March.
One report claims that Tierney could miss as many as three months of action (Evening Standard). He faces surgery according to the report and could be missing until March.
Steve Clarke wil be left with fears over this news. Tierney is a crucial player for Scotland and they’ve missed him since March 2018. To miss him for two potentially defining matches would be a blow.
After his early injury woes at the Gunners, already Tierney faces more time on the treatment table.
