Swiss international Johan Djourou has passed his fitness test and will be available for the squad to face Wolverhampton tomorrow, according to Arsenal's official website. The center back had injured his knee against Newcastle last Saturday and initially looked to be quite injured, possibly severely.
No reports came from Arsenal regarding his injury initially after the Newcastle match, and Djourou left for international duty shortly thereafter. All news regarding his knee thus came from the Swiss FA, and initial reports of "merely severe bruising" were already more positive than most would have hoped.
Song injured his thigh in the match against Everton, but is expected to be back tomorrow as well.
Denilson is back, and Cesc Fabregas and Robin van Persie have both recovered from illness.
Abou Diaby is injured and suspended.
Tomas Rosicky, sadly, has injured his groin while away with the Czech Republic; given his injury history, hopefully this isn't going to be too much of a problem. He did score in his match, so hopefully that can continue instead of his muscle problems.
