A rematch doesn't currently make sense.

There was no title on the line and Thompson would now demand much more money which means Price takes much less. It wont be easy to immediately re-sell and Thompson has zero following in America, he's an undercard fighter, the fight wasn't even shown on TV, so it defintely isn't going over there. And should Price lose again he's finished.

The only way they'll rematch is - Price wins a couple of comeback fights and Thompson beats Tyson Fury (a fight that does make sense). Then it will be much bigger than the first (which wasn't a big deal).
