The Wolfsburg midfielder is struggling with injury while Jon Dahl Tomasson is also doubtful for the match.

The Feyenoord striker was absent from yesterday's training session and was to be assessed today.

Goalkeeper Thomas Sorensen, defender Simon Kjaer and striker Nicklas Bendtner are already missing as Denmark complete their preparations for their Group A matches against Holland, Cameroon and Japan.

Arsenal striker Bendtner has been struggling with a groin injury and has been frustrated at having to train by himself.

"It has been quiet and not as planned," he said on www.dr.dk.

"It has not been fun to run around by myself."
