I don't think Wright and Hatton could find a weight, Winky has been fighting at 160 +/-, Hatton can't reasonably make anything near that, and i don't think Winky can get down to 147.
As much as i hate to say, Ricky's star has peaked. There really isn't a big fight for him at his ideal weight, maybe if Pacquiao disposes of Marquez and moves up a bit, that might be a good one, but other than that, there isn't much left for Ricky
