Jack Wilshere is set to miss today’s trip to Everton but he could be out for much longer.
According to The Telegraph, West Ham are unsure of the extent yet and it could vary from one week to three months.
Wilshere, who joined West Ham from Arsenal in the summer, is sitting out of today’s match at Goodison Park.
He was withdrawn from training in the week with a ‘minor’ ankle injury, but the Hammers physios are concerned.
Ahead of his assessment on Tuesday, a senior club source told The Telegraph: “It could be one week, it could be three months.”
Chronic injury concerns

Wilshere’s career so far has been riddled with injuries. Consequently, these have held back his progress.
At Arsenal, he burst onto the scene as a promising young player but has spent sizeable periods of time out injured.
This has also held back his England career and he is trying to earn his place back in the senior set-up.
West Ham need Wilshere

Wilshere needs to prove he has overcome his injuries to resurrect his stalling career and earn an England recall.
But the Hammers also need Wilshere to be fully fit and firing on all cylinders.
After four consecutive losses, West Ham sit bottom of the Premier League on zero points.
Manuel Pellegrini needs a player to step up and inspire the Irons off the foot of the league and Wilshere has the potential to fill those boots.
The sooner he returns to full fitness, the better for West Ham, as long as he is on his best form and ready to battle.
