Arsenal manager Arsene Wenger has confirmed that midfielders Francis Coquelin and Tomas Rosicky are available for today's FA Cup game against Burnley.
The 35-year-old Czech underwent knee surgery last summer and is yet to feature for the Gunners this season.
Coquelin has been out since November but is expected to feature against Sean Dyche's men.
"[Per] Mertesacker is out because of the red card," Wenger said.
"Everybody else is available, apart from Jack Wilshere and Santi Cazorla. After that it is just a question of selection and decision-making, that is the key.
"Jack and Santi are progressing well but they are at least a few weeks away. But these two apart, it is just about competitiveness and match fitness.
"Danny Welbeck is not completely ready but he is not far. He needs a game or two because he's been out since last April. The Stoke [under-21] game is too soon because he only had one session with the team, and that is too short.
"Francis [Coquelin] is available to play now because he has passed two weeks of full training. Tomas [Rosicky] is also available for selection."
