The French full-back lasted just a quarter of an hour after he was forced off during the Gunners’ game with Bournemouth
Mathieu Debuchy suffered a cruel injury blow on Sunday as he limped out of the game against Bournemouth after just 15 minutes.
The 31-year-old had not started for the Gunners in a year, spending the second-half of last season on loan at Bordeuax, but saw his Arsenal comeback cut short when he went down with a hamstring problem.
Arsenal had just taken the lead through Alexis Sanchez, before the France international was forced off injured. Arsene Wenger brought on Gabriel in place of Debuchy at right-back, and will await news on the severity of his injury.

Arsenal’s first-choice right-back, Hector Bellerin, is also currently sidelined, having been ruled out for six weeks with an ankle injury.
However, Bellerin could be in line for a return before Christmas, indicating that he is recovering well from the injury.
“It’s going better than expected because it’s a pretty hard injury but, at the moment, it’s recovering really well,” Bellerin told 101 Great Goals earlier this week
“I hope to be running by the end of this week or the beginning of next week and then we’ll just take it from there.”
