Arsenal midfielder Jack Wilshere has suffered another stress fracture to his ankle but has not been ruled out for the season, Press Association Sport understands.
The 20-year-old was first troubled by an ankle problem while on international duty with England last summer and, apart from a pre-season appearance in the Emirates Cup, has not played a competitive match for the Gunners this season.
Wilshere, who needed surgery after initially wearing a protective boot, was set to return in early February, but felt pain when running in training last week.
It is understood he has suffered a small stress fracture in his right ankle and that he is being monitored ahead of a scan on the injury in two weeks' time.
Wilshere is healing well from his original injury and has not been ruled out for the season.
The fitness of the combative midfielder will be of interest to England manager Fabio Capello as he prepares for his side's Euro 2012 campaign in Poland and Ukraine this summer.
Wilshere later tweeted: "I can confirm I have a stress fracture but it is not in the same area as my first injury which has healed very which I am happy about...
"I have developed a stress fracture in the Heal (heel) 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!"
