Arsenal winger Bukayo Saka is expected to spend three to four weeks on the sidelines, according to a report from BBC Sport.
Arsenal have made a strong start to their Premier League campaign, securing wins in their opening two matches against Manchester United and Leeds.
The 23-year-old was forced off during the second half of Arsenal’s 5-0 win over Leeds United, sparking concern among supporters and staff.
Saka appeared to pick up the problem in the 53rd minute and was replaced by Leandro Trossard.
Before leaving the pitch, the England international had already made his mark, scoring in the 46th minute to extend Arsenal’s lead.
His early exit, however, has raised fears about the club’s attacking options for the coming weeks.
There is a sense of relief that the issue is not long-term, especially after Saka missed three months last season with a hamstring injury.
Key fixtures in doubt as Arteta seeks solutions
The injury will force Saka to miss Arsenal’s crucial trip to face reigning champions Liverpool, a match that could shape the title race. He will also miss England’s upcoming World Cup qualifying fixtures.
Mikel Arteta will hope the recovery period does not extend further as Arsenal look to avoid a repeat of last season’s struggles when injuries hurt their campaign.
Fortunately, Arsenal have depth in wide positions. Players such as Gabriel Martinelli, Leandro Trossard, Noni Madueke, Ethan Nwaneri, and Max Dowman are available to cover for Saka during his absence.
In another setback for the Gunners, club captain Martin Ødegaard is a doubt for the clash at Anfield after suffering a shoulder injury against Leeds.
The Norwegian midfielder left the stadium with his arm in a sling after being substituted in the first half.
Ødegaard has not yet been ruled out of the trip to Liverpool, and there is optimism within the club that neither he nor Saka will face a lengthy spell out.
Both players remain vital to Arsenal’s push for the Premier League title this season.
