This matchup was done a few months ago. Honestly, based on styles, I think Lucas would've stopped Hatton late.
It would depend on how Mathyssee deals with the rough and tumble style of Ricky. Hatton had an annoying way of getting inside, holding and hitting, and basically wearing you down for the long haul. He would make you burn energy and it would be hard for his opponents to get the leverage they wanted on their shots. It would be a good one that's for sure.
Hatton would have humped, held and attempted to make love to Matthhyyyyssssee and won an ugly, controversial decision If he traded with him, he'd get laid out
