Newcastle United goalkeeper Rob Elliot has been passed fit to face Arsenal.
In-form Elliot missed Monday's 1-0 defeat to West Bromwich Albion at The Hawthorns with a stomach bug.
But the 29-year-old will be back in Steve McClaren's starting XI at the Emirates Stadium this afternoon (3pm kick-off).
And Cheick Tiote replaces the injured Vurnon Anita (hamstring) in midfield.
Relegation-threatened Newcastle are two points adrift of safety in the Premier League, while Arsenal lead the table.
ARSENAL: Cech; Bellerin, Mertesacker, Koscielny, Monreal; Flamini, Ramsey, Ozil; Chamberlain, Walcott, Giroud. Subs: Ospina, Gibbs, Gabriel, Chambers, Campbell, Iwobi, Reine-Adelaide.
