Arsenal fear Bukayo Saka could miss a minimum of six weeks with the quadriceps injury he sustained in their Champions League tie against Bayern Munich.

The 25-year-old will undergo an MRI scan on Friday afternoon to better assess the problem, which forced him off in Wednesday's 2-2 draw at the Allianz Arena.

Fluid around the affected muscle has made diagnosing the injury difficult, but club medics are estimating, after early examinations, Saka will miss a minimum of six weeks and it could be even longer.

If those early concerns are realised, he will miss a clutch of key games for the Gunners, as well as England's forthcoming Uefa Nations League matches against Croatia and Spain.

"We need a few more scans and opinions from the specialists," said Arsenal head coach Mikel Arteta.

"When a player has to walk off the pitch, he is struggling to walk without any pain, and is restricted to movement; it is not a good sign. Let's be a little bit patient so we can give a definitive assessment.

"He's got another MRI as there was quite a lot of fluid in the area so it was quite difficult to understand the extent of the injury. We will know more tomorrow."

Saka will miss Saturday's home Premier League match against Everton, where second-placed Arsenal will hope to close a three-point gap on leaders Manchester City.

The Arsenal academy product has had fitness issues in recent months and his game time was managed at the end of last season, as well as with England at the World Cup, because of an Achilles injury he suffered in March.

He missed the March international break and seven games for the Gunners, but returned to help them lift the Premier League title for the first time in 22 years.

Saka started the Champions League final defeat by Paris St-Germain but was substituted after 54 minutes, and only started three of England's eight games at the World Cup - scoring a hat-trick in the 6-4 third-place win over France.

The forward also had surgery on a hamstring injury he picked up in December 2024, which kept him out for 101 days in the 2024-25 campaign.

He made 49 appearances as Arsenal won the title last term, despite a stop-start season. As well as the Achilles issue, Saka pulled out of a game in January against Leeds with a hip injury in the warm-up, while a hamstring problem also kept him out for about four weeks.

The fact Saka needs follow-up scans and is likely to be out for up to eight weeks is a major blow for Arteta and Arsenal.

The Gunners boss had been speaking about how the player had been adapting his positioning to be more of a regular goalscorer for the club in recent weeks and the winger has scored four goals in 11 appearances so far this season.

But now Saka has gone down with another muscle injury there are questions about whether he still has the robustness that made him a certain starter in the Arsenal team.

The 25-year-old had Achilles, hip and hamstring problems last season and underwent surgery on a hamstring injury in the previous season which kept him out for 101 days.

He also had his game time managed at the World Cup in the summer with England and Arteta acknowledged Saka's robustness and availability has "certainly been different in the last year or so".

Arsenal tried to sign a world-class forward to level up their frontline in the summer but were unable to do so, with unsuccessful pursuits of Vinicius Jr and Julian Alvarez.

They did bring in Greece international Christos Tzolis, but he is currently injured too.

That has left them with Noni Madueke, Eberechi Eze and 16-year-old Max Dowman as alternative wing options.

Teenager Dowman has had limited minutes this season but Arteta spoke glowingly of his talent and ability to impact matches.
