Arsenal defender Mathieu Debuchy suffered what looked like a serious injury during his side's game against Manchester City.
The Gunners were leading 2-1 when the Frenchman landed awkwardly on his left leg, leaving him writhing in agony on the ground.
After receiving oxygen, the 29-year-old was stretchered off to applause from all corners of the Emirates.
Arsenal overcame Sergio Aguero's first-half strike with goals from Jack Wilshere and Alexis Sanchez. City equalised shortly after Dubuchy's injury however after a Martin Demichelis headed effort.
