The Gunners have revealed that their Uruguay international midfielder is set for a lengthy spell on the sidelines, but others are returning to fitness
Torreira was given oxygen on the field before being carried off on a stretcher, with it immediately apparent that he had suffered a serious problem.
Arsenal faced an anxious waiting before discovering the full severity of his injury and it has now been revealed that the combative 24-year-old suffered a broken bone.
No timescale has been put on his recovery, but head coach Mikel Arteta will not be able to call upon the South American any time soon.
In the latest fitness update on the club’s official website, Arsenal said of Torreira: “Sustained fracture to right ankle during Portsmouth (a) on Monday.
“Awaiting further specialist reviews which will determine recovery plan.”
While Torreira will be seeing plenty of the treatment table over the coming weeks, Kieran Tierney has stepped away from it.
