Arsenal manager Arsene Wenger says midfielder Aaron Ramsey will be in the squad to face Queens Park Rangers.
The Wales international suffered a hamstring injury at the start of last month when the Gunners defeated Leicester City at the Emirates.
He returns after almost a month on the sidelines ahead of key away fixtures against Manchester United and Monaco.
"Aaron Ramsey is back in the squad," Wenger said.
"When you have a repetition of muscular injuries, in can put the handbrake on your body a little bit. To get rid of that is a psychological problem.
"I don't think he suffers from that, looking at him in training. Certainly, you lose a bit of confidence in your body."
Asked to give an update on his other players, the Frenchman said: "From Sunday against Everton, I don't think we lost anybody.
"We have to check Francis Coquelin with the medical people this morning in training to see whether he'll be available or not, but there's no obvious reason why he should not be available.
"Mathieu Flamini is not far away but not close enough. I think he will miss the next two games.
"He's [Jack Wilshere is] doing well but it takes some time to heal the wound after the surgery. It will take him a few days.
"It [the Manchester United game] will be too soon. I don't set any dates, but what is for sure is that for Man United he will not be available."
