Assaulted at work but employer fired both of us?

I live in indiana, me and this other hothead got hired on and I’ve been working for 6 months him 4 years no complaints about me but numerous about him. Saturday night he got in my face and pushed me because of a pallet, I didn’t do anything back to him I informed a supervisor. 

Monday the warehouse supervisor gets both our stories and determines that even though I’m the victim and never put my hands on the other person and there was a witness that saw him push me, he determined we both started an altercation and let us both go today on Tuesday after our shifts. 

Is this right? Fired for being a victim and reporting it? What can I do if anything
