The Gunners have revealed their Uruguay international midfielder is set for a lengthy spell on the sidelines, but others are returning to fitness.

Lucas Torreira is set to be sidelined at Arsenal for the near future, with the Gunners confirming that he suffered an ankle fracture at an FA Cup clash with Portsmouth.

The Uruguay international midfielder lasted less than 16 minutes at Fratton Park on Monday when he was felled by a strong challenge from James Bolton against Pompey and left writhing in agony.

Torreira was given oxygen on the area before being carried off on a stretcher, with it immediately apparent that he had suffered a significant issue.

Arsenal faced an anxious waiting before finding the complete seriousness of his injury and it’s now been revealed the 24-year-old suffered a broken bone.

No timescale was placed on his recovery, but head coach Mikel Arteta won’t have the ability to call upon the South American anytime soon.

In the most recent fitness update on the club official site, Arsenal said of Torreira: “Sustained fracture to right ankle during Portsmouth (a) on Monday.

“Awaiting additional specialist reviews that will determine recovery program.”

While Torreira will be seeing loads of the treatment table within the coming weeks, Kieran Tierney has resigned from it.

The Scotland global left-back has suffered an injury-ravaged debut effort in north west London, but has returned to full training and is back in contention for aggressive minutes.

His recovery could prove quite timely, along with other defensive choices still stuck on the sidelines as Sead Kolasinac is set to be out of action until the end of the month.

Arsenal have said of the Bosnian full-back: “Substantial strain to shoulder joint during Everton (h) on 23 February.

“Aiming to return to complete training by the end of March.”

Meanwhile, January signing Cedric Soares is nursing a knee complaint and isn’t expected to resume full training until after the Gunners have taken at a Premier League derby date with West Ham on Saturday.

Calum Chambers is the only other player unavailable to Arteta, together with the 25-year-old having seen his effort brought to a close with a serious knee issue.

Arsenal said of him: “Ruptured anterior cruciate ligament of his left knee during Chelsea (h) on 29 December.

“Successful operation completed. Rehabilitation process expected to take between six to nine months.”
