The injury Alex Hleb picked up at Tottenham on Wednesday night will keep him out for "a good four weeks".
The Belarus midfielder came on as a 56th-minute substitute with Arsenal trailing 2-0 and helped Arsène Wenger's side complete a stirring comeback. However he hurt his hamstring late on and was replaced himself with four minutes to go.
Jeremie Aliadiere (back) and Emmanuel Eboue (ankle) also picked up knocks at White Hart Lane. They may miss Sunday's FA Cup tie with Bolton but should be available for the return game with Tottenham next Wednesday.
However the prognosis for Robin van Persie is not so clear-cut. When the Dutchman broke a metatarsal in his right foot in Sunday, Wenger suggested the striker might be out for six weeks. He now admits that might be optimistic and suggested he could be out for as many as 10 weeks. However, when he spoke to Arsenal TV Online on Thursday, the immediate concern was Hleb.
"I think he will be out longer than I thought last night," said Wenger on Thursday afternoon. "It will be a good four weeks.
"That is the disappointing side of last night. It puts our performance into perspective. You don't want to lose players in January because, if you lose them for a long time, then their season can be over.
"We also lost Jeremie but that is a question of days. I think he will be able to play on Wednesday. Also Eboue has done his ankle again. That is only minor too and I hope he'll be fit for Sunday but if not Wednesday."
The manager could not be so optimistic about Van Persie.
"Ideally you would say six to eight weeks but as well it could be 10," he remarked. "That means April and you are close to the end of the season and you'll need to get back to your best level. I hope it will be six weeks but that is really optimistic."
Arsenal TV Online subscribers will be able to see the full video interview on Friday morning. In it the Arsenal manager discusses: the comeback against Tottenham, why Julio Baptista is like Robert Pires, his side for next week's second leg, Gareth Bale, Ray Parlour, the FA Cup's return to Wembley, balancing the FA Cup and the Champions League.
