Petr Cech will start in goal for Arsenal at Sheffield Wednesday tonight in the League Cup fourth round as David Ospina (shoulder) remains out.
The Gunners have no fresh problems following Saturday's defeat of Everton, but defender Per Mertesacker is available again following illness.
Aaron Ramsey (hamstring), Mikel Arteta (ankle), Jack Wilshere (fibula), Danny Welbeck and Czech midfielder Tomas Rosicky (both knee) all continue their rehabilitation.
Meanwhile, the Gunners have been fined £60,000 and warned over their future conduct after breaching Football Agent Regulations in the transfer of Calum Chambers from Southampton, the English Football Association has announced. Chambers moved from Saints to the Gunners in July 2014 for an undisclosed fee, believed to be in the region of £11million.
Agent Alan Middleton was fined £30,000 and suspended for three months for his part in the same matter.
However, the suspension is suspended for 18 months from October 23, 2015 "unless he commits an offence contrary to the agents regulations or The FA's regulations on working with intermediaries during this time," the FA said.
Meanwhile, Wednesday manager Carlos Carvalhal hopes to bring the big names back to Hillsborough on a regular basis after savouring the visit of Arsenal.
The Owls have not been among English football's elite since 2000, but they sit ninth in the Sky Bet Championship, unbeaten for eight games, and Arsenal's arrival in South Yorkshire tonight provides a ready link to their past.
In 1993 they reached the final of both the FA and League cups, losing to the Gunners in both competitions, with the former competition decided on replay.
"This game will be a fantastic day for Sheffield Wednesday," he said. "The fans will remember the past, the old past, but we hope that can be the normal again in the future.
"A full stadium, a game on TV. This is why I'm happy and the players are happy, because we are working towards this."
