The 27-year-old has been a key figure for an Arsenal side that have only conceded five goals in their opening 11 Premier League games.
Gabriel was furious as he limped off the pitch with his side 2-0 up in the 64th minute, with Mikel Arteta’s side sweating over the extent of his injury.
The Brazilian Football Confederation (CBF) has now confirmed that he will miss their game against Tunisia on Tuesday due to the muscle injury.
Their statement reads: "Arsenal player Gabriel Magalhaes was re-evaluated this Sunday (November 16) and underwent imaging tests that revealed a muscle injury in his right thigh. Therefore, the player will not be travelling with the team to the match against Tunisia in Lille. No other player will be called up to replace him."
Arsenal could now be without one of their most important players for the North London Derby, their first game back from the international break.
