The Brazilian has been central to the Gunners’ defensive resilience and remains a constant threat from set pieces.
Gabriel was forced off an hour into Brazil’s 2-0 win over Senegal at the Emirates Stadium and subsequently withdrew from the squad, prompting immediate concern.
According to The Athletic, further tests on his right thigh are planned, but early fears suggest he could miss up to two months, ruling him out for the rest of the calendar year.
He joins an injury list already featuring Martin Odegaard, Viktor Gyokeres, Kai Havertz, Gabriel Martinelli, Noni Madueke and Gabriel Jesus.
Despite setbacks, Arsenal have still climbed to the top of the Premier League table, opening a four-point gap over Manchester City.
