Arsenal could be without Noni Madueke for their next two games, according to The Athletic.
He picked up a knock while on international duty last Friday, and the Gunners are sweating over his fitness in a potential blow to manager Mikel Arteta.
Madueke sustained a knee injury against Uruguay and left the stadium wearing a left knee brace.
The Arsenal attacker also picked up a knock during an accidental collision in training two days before the Carabao Cup final.
He left Wembley Stadium with a significant strapping on his left wrist after playing the game with a cast.
Arsenal resume action on Saturday with a trip to Southampton for their FA Cup quarter-final tie. They face Sporting CP in the Champions League three days later,
The 24-year-old will likely miss both games, but could be available for their next Premier League fixture against Bournemouth at the Emirates Stadium on April 11.
Jurrien Timber, Gabriel Magalhaes, Eberechi Eze, William Saliba, Martin Zubimendi, Piero Hincapie, Leandro Trossard, Declan Rice and Bukayo Saka also pulled out of international duty.
Mikel Merino and Martin Odegaard are currently unavailable due to injuries, but the latter is expected to return very soon.
Arsenal will be desperate to win the Premier League title, having led their rivals at the top of the table for most of the season.
They need a fit squad to get the job done, and Arteta will be praying for some good news.
