I wouldn't be surprised if Helenius folded quick under pressure, however, Whyte has fancied himself as a boxer ever since the AJ fight. If he tries to box at range I can see him coming off second best needing to walk through the Finn and rough him out of it.

The Finn's weight will be a good indicator. His pomp weight was always around 240, his bad spell he's been 260-ish. He doesn't come across as very confident mind...
