Arsenal midfielder Jack Wilshere played his first game in 10 months as he started for the Gunners’ Under-21 side against Newcastle on Friday.
The England international has not featured for club or country since June 2015 after fracturing his fibula.
The 24-year-old was initially expected to be out for three months.
Arsenal have seven Premier League games remaining this season, while England manager Roy Hodgson will name his Euro 2016 squad on 12 May.
The return of Wilshere will be a boost for Hodgson, particularly as it came on the day that another England midfielder, Jordan Henderson, was ruled out for the rest of the season with a knee injury.
Wilshere played 65 minutes as Arsenal beat Newcastle 3-1 in an U21 Premier League game at Emirates Stadium.
Another long-term injury absentee, Tomas Rosicky, also featured as he continues his comeback.
The Czech Republic midfielder, 35, has been out with a thigh problem and has made only one first-team appearance this season.
