Manchester United winger Nani has been ruled out for 10 days with a hamstring injury.
The Portugal star suffered the problem during Wednesday's Champions League 3-1 victory over Braga.
"Nani is out with a tight hamstring. It will be about 10 days," said boss Sir Alex Ferguson.
"Jonny is a doubt," said Ferguson.
"It is not a serious one. We are monitoring it and hopefully he will be OK."
