Arsenal have been dealt a double injury blow as Wojciech Szczesny and Lukasz Fabianski both suffer setbacks.
According to Goal.com, Gunners first-choice stopper Szczesny is struggling to recover from an ankle injury, while back-up keeper Fabianski has been ruled out for three months with ruptured ankle ligaments.
Reports claim Fabianski broke down in training on Tuesday, just as he was closing in on a return to the Arsenal first-team after a long lay-off.
Szczesny has been on the comeback trail for the past few weeks, and has been wearing a protective boot for the last 10 days to accelerate the healing.
But the Polish number one, who has already been out for a month, is still around two to three weeks away from making a return after suffering a slight setback.
The Polish duo's absence has opened the door to Arsenal number three Vito Mannone, and the Italian keeper has shone in the Gunners net.
The academy graduate has put in a series of impressive performances, and kept a number of clean sheets, leading to speculation he may have played his way into being named Arsenal's number one on a permanent basis.
Fabianski was reportedly set to be named in Arsenal's squad to face Norwich on Saturday, but the Polish international will now rejoin Szczesny on the physio table.
That double injury blow leaves Mannone as the Gunners one senior keeper - the 24-year-old Italian backed up by Argentinian youngster Damien Martinez and youth team shot-stopper James Shea.
