ARSENAL star Danny Welbeck was given oxygen and carried off the pitch on a stretcher after suffering a horror leg injury against Sporting Lisbon.
The Gunners striker went up for a header midway through the first-half against Sebastian Coates and landed awkwardly.
Welbeck smashed the ground in agony after the incident, as medics ran on to the pitch to his aid.
Mesut Ozil tweeted support for his teammate, writing: “Oh no … get well soon Danny.”
Arsenal legend Martin Keown, a pundit for BT Sport, said at halftime: “When you see that on the pitch it is always a bit shocking. It reflects on the players’ faces.
“He is one of the nicest men I’ve met in football. He is the heart and soul of the football club and he’s been desperately unlucky with injuries.”
It could well be his last appearance for the Gunners if the injury is as first feared.
