Arsenal fear Petr Cech will miss this week’s North London derby through injury.
The Gunners take on Tottenham on Saturday knowing a defeat will provide a major blow to their hopes of securing a top four finish this season.
Victory will see them close the gap on Spurs to a single point in fifth, but a loss could see them slip eight points adrift of a Champions League spot.
And they could be forced to go into the crucial match at Wembley without the services of their dependable first choice keeper.
Cech suffered a calf injury in the 5-1 win over Everton last week which forced him to limp out of the game midway through the second half.
Boss Arsene Wenger initially said the injury looked like a kick on the calf, and the Gunners appeared unconcerned over his fitness going forward.
But it is understood scans indicated more damage than initially feared and the medical team fear he will not recover in time for the Tottenham game.
