Arsenal forward Danny Welbeck has been ruled out for nine months after undergoing surgery to repair cartilage damage.
This was revealed on Wednesday by Arsenal on their official website.
The former Manchester United player sustained the injury in Arsenal's 2-2 draw against Manchester City at the Etihad on Sunday.
He is now automatically ruled out of the European Championship kicking off next month in France.
Arsenal said in a statement: "Danny Welbeck has had surgery to his right knee.
"Specialists determined surgery was required after scans and tests revealed significant cartilage damage.
"The 25-year-old was injured during Sunday’s match at Manchester City. Danny will miss the Euro 2016 Championship in the summer and his full recovery is expected to take approximately nine months.
"Since returning to action in February after injuring his left knee in May last year, Welbeck’s impact has been telling – scoring five times, including the recent winner against Norwich City at Emirates Stadium.
"Everyone at Arsenal will be working hard with Danny throughout his recovery and look forward to seeing him back on the pitch as soon as possible."Jiji.ng the cheapest online shopping in Nigeria
