Look, I'm not a doctor. I'm actually the other profession on this site (lawyer) that typically fights each other like the bicycle jousting scene in Quick Change. But are we really going to say that a lacerated liver is evidence of the hit being extra malicious? I think the hit is dirty, but nothing more than your run of the mill hard hit that players will eat the flag on just to get into the other team's head. Organ damage is sometimes a freak byproduct of a hit (Chris Simms, Steve Edmonds, Damar Hamlin) and I don't think that severe injury was the intended result.
He came in hard and popped Hunter in an almost bang/bang play. He could have pulled up, but wanted to get a hard hit in during a game with a lot of chirping. That's football, per Deion himself. This isn't in the same ballpark, to my eye, as other obvious dirty cheap shots like Kellen Heard on Colt McCoy nor does the CSU player seem to have a history of dirty shots preceding this one like the Burfict hit on Antonio Brown.
