Arsenal boss Arsene Wenger says midfielder Jack Wilshere is in the squad to face Swansea City on Sunday.
The Englishman missed the mid-week Champions League game but is expected to be in the starting line-up against Garry Monk's side.
"[Mikel] Arteta will be out for Sunday. He has a mild hamstring strain and he will be out for a short period because it's a grade one. He should be back after the internationals," Wenger said on Friday.
"[Olivier] Giroud joins in training next week. Jack [Wilshere] is alright, he is back in the squad for Sunday.
"[Mathieu] Debuchy, [David] Ospina and [Mesut] Ozil are progressing very well, but of course they are not available before or straight after the international break.
"Laurent [Koscielny] has a little chance to be back after the international break.
"He [Theo Walcott] is now ready to play again and we just have to leave him in peace and give him the time needed to come back.
"He has been out for 10 months - I don't know if you realise how long that is. People think it's like mechanics.
"[Players are] not machines, they are human beings and to get back into the rhythm of the top, top competition will take time."
