Arsenal boss Arsene Wenger says Jack Wilshere has had an "exceptionally good" scan as he continues to recover from an ankle injury.
The 19-year-old suffered the injury in the Gunners' pre-season friendly against New York Red Bulls on 31 July.
The England midfielder had successful surgery in September.
Wenger said: "Jack had a very important scan, it was exceptionally good and the news is positive. He could be back in mid-February."
Wilshere later tweeted: "I can confirm what the boss said that I had an exceptionally good scan on tuesday and I can now step up my rehab and start jogging!"
Wenger also had good news about Kieran Gibbs, who could make a return from a hernia problem over the Christmas period.
Left-back Gibbs had surgery in November but is set to be available for the trip to Aston Villa on 21 December.
Wenger said: "Gibbs is a maximum of one week away. He could be present at Villa or the game after. You want him back playing."
