I doubt this will happen even though Conor says it will and Manny's camp seem to suggest they're working on it. If they both need the money they should just fight people in their respective sports. Connor is a great MMA fighter but he's not going to beat a boxer despite Manny getting on a bit now. and being out of action for a while. Fans are desperate to see him in the UFC again so why not just give people what they want. No big boxing matches are going to take place anytime soon due to covid restrictions so he might as well fight in the UFC as at least Dana has managed to put fights on behind closed doors.
