Hasta La Motion!

i’ve removed green screen with ultimatte, but all the motion blur is mixed with the green screen, is there a way i can make the motion blur come back without the green showing or a way i can make the motion blur solid?spill suppress just makes it grey… or do i need to paint back objects?

i originally thought i could do a roto around the object and put a solid color in behind my green screen work and blend it in however the layers are not merging well probably due to grades/color correction. :/
