Anthony Joshua will be 21 pounds heavier than Jermaine Franklin when the two meet in their heavyweight contest on Saturday night live on DAZN.
Joshua was 255.4lbs on the scales while Franklin was considerably lighter at 234.12lbs.
This huge difference in weights may give an insight into their respective strategies.
With Joshua being heavier man, it's likely that he will opt for a destructive gameplan as he looks to make a statement to the rest of the heavyweight division.
But Franklin, meanwhile, seems to be wanting to utilise his movement and attempt to stay out of Joshua's range, and this can only be achieved with a lighter frame.
Now all eyes focus on the O2 Arena on Saturday night, where Joshua hopes he can kickstart this new era of his career with a bang.
