Theo Walcott is expected to recover from a mild hamstring problem in time for Arsenal's FA Cup fifth-round tie against Leyton Orient on Sunday.
Walcott sustained the injury in Wednesday night's 2-1 Champions League victory over Barcelona, but manager Arsene Wenger predicts the England winger will make a swift recovery.
"We have a little concern about Walcott's hamstring but it should be all right," Wenger told Arsenal TV online.
Centre back Johan Djourou is sidelined for the trip to east London after suffering a back problem at the Emirates.
Right-back Bacary Sagna is available after being suspended against Barcelona but midfielder Abou Diaby is still banned.
Striker Marouane Chamakh will return to the squad after missing out on Wednesday.
