While most likely just a joke, in the commentary track for 'Avengers: Infinity War', it was hinted that Cull Obsidian's severed hand would appear in 'Agents of S.H.I.E.L.D.'.

They probably joked about it, in the sense how the show usually brings up stuff to tie themselves back to the movies, unlike the others shows which try to tell their own stand-alone stories.
