Bukayo Saka had to leave against Manchester City, but avoided a serious injury.
The England international limped off with almost 15 minutes remaining against City at the Etihad Stadium on Easter Sunday.
An Arsenal physio had to escort Saka while holding his leg and he looked unhappy when Gabriel Martinelli replaced him.
However, Mikel Arteta shared a positive update on the England player ahead of the Gunners' match against Luton.
He said: “He just came out tired today, nothing serious.”
This is important for Arsenal as they have some crucial games coming up in the Premier League and Champions League.
The 22-year-old has been one of the most key players for Arsenal this season, as they look to finish the year with silverware.
Saka has only missed one Premier League match for the north London side this campaign.
In 37 appearances in all competitions, the winger scored 16 goals and also assisted 13 times.
While Arsenal were unable to achieve a win at the Etihad, a draw is by no means a bad result and keeps them second in the Premier League.
Earlier, Liverpool had taken the lead in the title battle after coming from behind to beat Brighton at Anfield.
But it is still tight at the top with three points separating third-placed City and Liverpool.
