Arsenal management are upbeat over Danny Welbeck's latest injury setback.
The Daily Mail says Arsenal are hopeful Welbeck's latest injury is not serious following a scan on Monday.
The England star, on his return to action following a four week layoff with a groin injury, limped off against Watford with a hamstring problem.
Laurent Koscielny, who came off with cramp at the weekend, is expected to be available for the weekend game against Everton.
So too are Alexis Sanchez and Aaron Ramsey who missed the loss against the Hornets with respective thigh and hamstring injuries.
