A cleaning shoe material-other-than-grain (MOG) discharge system of a combine harvester has a thresher rotor assembly configured to produce a stream of thresher rotor MOG and a shoe disposed beneath the thresher rotor assembly configured to produce a stream of shoe MOG. A chopper receives and chops the stream of thresher rotor MOG. Vanes disposed at an outlet of the chopper distribute the chopped thresher rotor MOG. A plate having top and bottom surfaces is adjacent to the plural vanes. A duct is set on the plate, the duct having a first inlet and a first outlet, the first inlet disposed adjacent to an outlet of the shoe to receive the stream of shoe MOG, the first outlet disposed downstream of the outlet of the chopper such that the stream of shoe MOG is received in the stream of chopped thresher rotor MOG.
