Arsenal striker Thierry Henry has only a 30 percent chance of being fit for the north London derby at Tottenham Hotspur on Saturday.
"There is a bit of uncertainty about Thierry," manager Arsene Wenger told Arsenal TV Online on Thursday. "He has had a little bit of a setback.
"We pushed him in a little early and we need to get him completely back to where he can perform. At the moment he is not there, he is 30 percent to play (against Tottenham) and 70 percent not to play."
The French international returned to the side as a 16th-minute substitute against Sparta Prague in the Champions League on October 18 after being sidelined for six weeks with a groin injury.
Henry scored twice in a 2-0 win in Prague to overhaul Ian Wright as Arsenal's record goalscorer.
