The 22-year-old striker left Carrington on crutches and will miss Sunday's Premier League clash with Blackburn and most likely their remaining two group matches in the Champions League.

England coach Steve McClaren had only just named Rooney in his squad and greeted the news with understandable disappointment.

"But we have to deal with it, like we have dealt with situations like these before. It is an opportunity for someone else to come and do a job."
