This shouldn’t be that good of a fight as Rozicki is a young cruiser weight with a lot of power while Louis is 38 and is very washed up at this point of his career. Rozicki is 12-0 with 12 knockouts while Louis is 8-6 with four knockouts.
Louis retired in 2016 but came back earlier this year and lost in quick fashion against Oscar Rivas. He really didn’t look good in that fight and was retired on his stool after three rounds.

I think Ryan Rozicki will win by knockout very early due to being in his prime and having much more power.
