The Brazilian walked off during Arsenal's 2-1 win over Sevilla
Gabriel Jesus will undergo scan in the next couple of days for a potential hamstring injury.
The forward limped off the pitch in the 81st minute of the 2-1 win over Sevilla. Jesus scored Arsenal’s second goal, which gave them the win and secured their place at the top of the Group.
Speaking after the game, the 26-year-old expressed his optimism that the injury is noting serious and it is just a routine check.
“I felt something. Let’s see. I did some tests with the physio, it looks not that big, but let’s see. I have a scan, maybe tomorrow. I’m pretty sure it will be nothing.” he said.
Arsenal go against Sheffield United in the Premier League on Saturday, before visiting West Ham 4 days later.
