Arsenal have been handed an injury scare after Sead Kolasinac limped off towards the end of Bosnia's draw with Senegal.
The left-back started the match but suffered an apparent knee injury when he was kicked during the second half and was replaced 20 minutes from time.
The 24-year-old missed 3 games during January due to an ankle problem.
The German native has played 31 times for the Gunners this season. He signed as a free agent from Schalke in the summer.
