Ankle injury has sidelined Arsenal midfielder Lucas Torreira after he suffered a fracture ankle in their 2-0 FA Cup victory over Portsmouth.
The Uruguayan International was stretched off in the clash with Arsenal yet to announce his possible return as he faces further specialist reviews.
Similarly, Sead Kolasinac has been ruled out until end of March with a shoulder injury.
Portuguese international, Cedric Soares is yet to make his debut for the Gunners after signing on loan from Southampton. The 28 year old will have to be patience for more weeks before being available for full training.
However, the return of 22 year old full- back Kieran Tierney to full training after dislocating his shoulder in December, has been a boast to the squad. The first season of the former Celtic defender with the Gunners has been ruined by injury.
