The host Pirates will counter with left-hander Francisco Liriano.
The Reds hope Latos will improve with treatment and will be able to pitch in the National League Divisional Series if they win on Tuesday.
Manager Dusty Baker was considering starting Latos in the wild-card game but the right-hander has been bothered by pain in his elbow.
With Cueto starting, Latos will probably not be on the Reds' roster for the game. He may return if the Reds win Tuesday's game.
