MANCHESTER, England -- Manchester United striker Wayne Rooney's injury layoff because of a knee problem has been extended by another two weeks.
The England international was hurt in training on Dec. 25 and was initially expected to be back in training by now.
Manager Alex Ferguson says "Wayne is still injured. It is not serious but it is going to take longer than we thought, probably another two weeks."
United hasn't specified which knee was injured.
But there was some good news for United with Ferguson saying winger Nani, who has been absent for two months because of a hamstring problem, would start training again on Friday.
