I wouldn't be surprised if Haye wants to go out on a "win" in front of some of his fans. It won't be billed as that, it we be another comeback and it will be a pee poor opponent and a week or two after that Haye will make a retirement announcement.
I don't mind seeing Dave back on Dave, as long as he walks out to I Love the Sound of Breaking Glass and not Ain't No Stoppin Us Now.
