"We are really sorry for this, really disappointed, when players have an injury I hope they can recover well and soon."
Brazil held a 2-0 lead over Senegal when Gabriel's participation was curtailed.
Chelsea winger Estevao broke the deadlock, whilst Manchester United midfielder Casemiro extended their lead.
Tottenham also suffered a fitness concern in the same fixture.
Pape Matar Sarr was withdrawn with his own injury early in the second period following a collision with Brazil's United striker Matheus Cunha.
Gabriel has emerged as a key figure in Arsenal's impressive start to the season, and his potential absence could be a significant setback for Mikel Arteta's table-topping side.
He has been an ever-present in the Gunners' Premier League campaign, netting a crucial late goal at Newcastle in September and helping to establish the tightest defence in the top flight.
Should he fail to recover in time for the derby, it could pave the way for Piero Hincapie to make his first league start. The summer recruit from Bayer Leverkusen was deployed as the left-sided centre-back in Arsenal's Carabao Cup triumph over Brighton last month but has seen limited action in the league thus far.
