Arsenal are in for a nervy wait after Gabriel Magalhaes was substituted by Brazil with an injury during their friendly against Senegal.
The towering centre-back, who is in the best form of his life for The Gunners, clutched his groin as he was hooked by Carlo Ancelotti under the lights at the Emirates.
He appeared in some discomfort after taking a knock on the 63rd-minute during the match held in North London, where he has put on some exceptional performances throughout this season.
Flanked by medical staff, Gabriel slowly trudged off the pitch and looked dismayed as he was replaced by Roma defender Wesley.
