Arsenal striker Emmanuel Adebayor faces three weeks out after damaging his hamstring in the goalless draw with Tottenham Hotspur on Sunday.
"Adebayor is out for three weeks with a hamstring," manager Arsene Wenger told the club's website.
The Togo striker pulled up sharply after 35 minutes of the north London derby and is now a doubt for Arsenal's Champions League last 16 tie against Roma later this month.
The better news for Wenger is that Croatia striker Eduardo was on the bench against Spurs for the first time since he suffered a broken leg almost a year ago.
"We have Carlos Vela, we have Nicklas Bendtner, we have Eduardo we have Andrei Arshavin and we have Robin van Persie. We have plenty of strikers," Wenger said.
