Arsenal manager Mikel Arteta is hopeful Bukayo Saka won't be out for long after the youngster limped off against Brighton on Tuesday night.
The 19-year-old was influential once again but was withdrawn with nine minutes to go, moments after assisting Alex Lacazette's winner.
Speaking after the match though, Arteta revealed it was nothing serious, before going on to praise him after he helped Arsenal record their second successive win.
"He was limping," Mikel Arteta said. "He took a strong challenge but hopefully he will be okay.
"Today he had a difficult game in the first half because we weren’t using certain moments to generate advantages for him and other attacking players in the right way, so the game became really difficult back to goal against a back five in a really low block.
"In the second half, the moment we started to play different was an attack in a different way where they found more space and capacity to unlock the situations and their block. We created four or five big chances and he was involved in most of them."
The win saw the Gunners move to 13th on the table, and will look to build on the same when they visit West Brom on Saturday.
