Arsenal boss Wenger facing major keeper crisis
The Daily Mail says Lukasz Fabianksi could face another three months out with ruptured ankle ligaments.
The Poland goalkeeper was hoping for a recall to the squad after being out since February with shoulder injuries but he damaged his ankle during training on Tuesday.
The latest setback for the 27-year-old means Vito Mannone, who began the season as third choice, will continue in goal with Argentinian Damian Martinez, 20, and James Shea, 21, as back-up.
First choice Wojciech Szczesny is still three weeks short of full recovery from his ankle injury.
