Boro boss Tony Mowbray has made the move to provide cover for Jason Steele, who has had surgery for a fractured bone in his wrist.
The loan deal comes after Ikeme played for Boro in their final pre-season friendly against PSV Eindhoven last Friday.
The 25-year-old is now set to make his league debut for Mowbray's side in their Championship opener with Portsmouth on Saturday.
The shot-stopper brings plenty of experience to the Riverside, having had previous loan spells with Sheffield United, QPR, Leicester, Accrington and Stockport.
