The centre-back limped off during a 2–0 friendly win over Senegal at the Emirates Stadium, prompting immediate concern for both club and country.
The incident occurred shortly before the hour mark when Gabriel pulled up off the ball, clutching his right thigh.
Medical staff provided on-pitch treatment before he was withdrawn from the match. Brazil manager Carlo Ancelotti offered limited clarity afterward, admitting the severity remained unknown. "He felt something in his adductor," Ancelotti said, noting that a full assessment would take place on Sunday. "We're very disappointed. You always hope a player recovers quickly."
The injury comes at a delicate moment for Arsenal, who sit atop the Premier League after building the joint-best defensive record in the division - five goals conceded in 11 matches. Gabriel has been instrumental in that foundation, forming a reliable partnership in the back line. His availability will be closely monitored ahead of the North London derby against Tottenham on 23 November, followed by a significant Champions League meeting with Bayern Munich just days later.
Brazil confirmed that no decision has been made regarding whether Gabriel will travel with the squad to France for their upcoming fixture against Tunisia. For now, the defender's status hinges on the results of further medical checks.
While Brazil's victory featured goals from Chelsea's teenage winger Estêvão and Manchester United midfielder Casemiro, Arsenal were dealt a second defensive update during the international break-this time concerning Riccardo Calafiori. The Italian defender left his national team camp after following an individual training programme designed to manage his workload. Italy manager Gennaro Gattuso explained that although Calafiori might have been able to feature, pushing him further "wouldn't have been fair to him or Arsenal." A source confirmed he has not returned to London for treatment.
As the international window continues, Arsenal now face an anxious wait over the condition of two key defenders. For a team built on defensive solidity, the coming days may prove pivotal in shaping their readiness for one of the season's most demanding stretches.
