Jack Wilshere has updated his twitter followers after sustaining a fresh stress fracture in his heal, with the Arsenal starlet admitting that he is yet to know how long it will take to fully recover.

Wilshere had already been recovering from injury, and was expected to make a return to action for the Gunners this month after receiving surgery last year.

But in a bid to make his long-awaited comeback, he broke down in training, and sustained another stress fracture to his right ankle.

The 20 year old will now most certainly miss Arsenal's season, and could also miss England's 2012 Euro campaign.

While Wilshere had been keeping Arsenal fans on twitter updated on his rehabilitation, the midfielder has now delivered news that will no doubt come as a blow to the club.

He wrote: "I have developed a stress fracture in the Heal now and I don't want to put any time scale on it as I do not know how long it will take...

"I will update you more in a couple of weeks when I know more!"

Wilshere moved from Arsenal's youth team to the senior squad in 2008, and after a loan stint at Bolton, he established himself as a potential future talent for the north London side.

The club confirmed on their official website today that Wilshere had received the stress fracture, but insisted he 'has not been ruled out for the remainder of the season'.

On a positive note, the scans reportedly revealed that Wilshere's original fracture is healing well, despite the setback, which is not necessarily uncommon when players sustain stress fractures.
