Arsenal have described Danny Welbeck’s right ankle injury as “significant” and will provide a further update in the next 72 hours.
Unai Emery admitted the injury suffered by Welbeck during Arsenal’s goalless draw with Sporting Lisbon had an adverse affect on his players.
The Emirates Stadium stalemate was enough to seal progression into the latter stages of the Europa League – as they now target top spot in Group E.
A forgettable game was overshadowed by a first-half injury to England forward Welbeck, who was taken to hospital after being carried off on a stretcher.
Many of Welbeck’s team-mates appeared distressed as he received lengthy treatment and needed an oxygen mask after what appeared to be an awkward landing as he challenged in the air for the ball.
Emery, whose side extended their unbeaten run to 15 games by shutting out Sporting, conceded the situation weighed heavy on his players.
