Manchester United striker Wayne Rooney could be ruled out with injury for the Red Devils' home clash against Newcastle United on Saturday.
The 26-year-old was absent from Sir Alex Ferguson's side that drew 2-2 with Benfica in the Champions League last night.
"He wasn't fit [for the Benfica game], so we need to wait to see what he is like over the next few days," said Ferguson.
"We will give him every chance, of course - we did for this, but he wasn't really fit, so we'll just have to wait."
The Red Devils sit five points below Premier League leaders Manchester City.
