Jack Wilshere has handed Arsenal and England a significant injury boost by returning to training ahead of the final month of the season.
The 22 year old suffered a broken foot while on international duty against Denmark at the start of March and fears were rife the England international could be forced to miss the remainder of the campaign which would throw into doubt his participation in the World Cup this summer.
But Wilshere has made a full recovery from the foot injury to give Arsenal a huge boost ahead of the remainder of the campaign in which Arsene Wenger's side are pursuing a Champions League place and a first major trophy since 2005 in the FA Cup final against Hull City.
Wilshere posted an image at Arsenal's training ground at London Colney with the message: "First time in boots for 6 weeks!!! Great feeling!"
Arsenal's injury list has hugely damaged their Premier League title hopes with Aaron Ramsey, Mesut Ozil and Theo Walcott having spent long spells on the side-lines.
Though Wilshere will miss the Premier League visit of West Ham United he could be involved for Sunday's trip to Hull and the league meeting against Newcastle United on 28 April but Wenger says his return could be delayed.
"Jack Wilshere should start to jog this week," Wenger said on Monday. "It is all going well, but we have to monitor him now day by day. The next three weeks will be very important for him. Can he play this season? Yes."
Having endured constant injury problems, Wenger is expected to be cautious over Wilshere's return with the midfielder having spent 14 months out with an ankle problem before returning in September 2012.
Both Tomas Rosicky and Laurent Koscielny are doubts for Arsenal ahead of the game against West Ham on Tuesday after undergoing fitness checks.
