A deleted scene from Star Wars: The Force Awakens has appeared online and shows Chewbacca pulling off Unkar Plutt's arm after a previously unseen run in with Rey. 

It's a nice tough and homage to the original films where Han Solo famously tell's C-3PO to that it's not wise to upset a Wookie, because they have a habit of ripping peoples arms off when they lose.
