Arsenal captain Thierry Henry will be sidelined till early in the New Year through injury, coach Arsene Wenger said on Tuesday. "Thierry has started his rehabilitation. He is still not completely free from his hamstring injury so he starts again," he said. Asked if the France striker won't be ready until the New Year, Wenger said: "Realistically, certainly yes. I would not want to set a time on it. We will take the needed time." Henry has been out of Arsenal's last three matches, missing the 1-1 and goalless draws with Chelsea in the Premiership and Porto in the Champions League as well as a 3-0 victory over Tottenham. Arsenal will play Wigan on Wednesday in their postponed match and they can field Ivorian international Kolo Toure, who missed Chelsea's clash due to suspension. Czech Republic playmaker Tomas Rosicky and French defender William Gallas are still ruled out with different injuries. "We have Kolo back, but he's the only one from Sunday," said the French boss. "Gallas is still out but Rosicky looks very, very promising and has a small, small chance for the weekend."
