Arsenal’s Premier League and Champions League probabilities were dealt one more blow as Gabriel was forced off against Fulham.
With lower than quarter-hour played, the Gunners defender was holding the back of his leg with what seemed to be a hamstring injury.
Gabriel waved his hand within the air multiple times to signal his injury as play continued, with a Fulham corner bringing the motion to a halt.
Arsenal’s centre-back sat on the pitch and cut a pained expression before being substituted just moments later for Jakub Kiwior.
It’s an injury that would spell the tip of his season given there’s lower than two months left of the season.
And while Arsenal’s title hopes are faint, the injury to Gabriel may be very premature with the Gunners facing Real Madrid within the Champions League next week.

Gabriel could join teammates including Kai Havertz and Gabriel Jesus on Arsenal’s list of long-term absences.
Takehiro Tomiyasu and Riccardo Calafiori have also struggled with fitness throughout the season, with Arsenal losing grip on top spot.
Mikel Arteta and Arsenal fans now face an anxious wait to see how long Gabriel will likely be sidelined for.
The Brazilian missed just two Premier League matches earlier within the campaign with a knee issue.
He has once more been a reliable asset within the Arsenal defence but may now be highly-missed throughout the run-in.
Despite his injury, the Gunners opened the scoring in a while in the primary half when Mikel Merino’s effort deflected in off a Fulham man.
