The read
Diniz's kickboxing pedigree and finishing rate make him live against anyone at heavyweight, and Boser now arrives off a stoppage loss of his own to Gokhan Saricam in April.
Expect Boser's chin and craft to be tested early by Diniz's power, with the home-country crowd squarely behind the Canadian.
The matchup
Two heavyweights with real knockout power meet in front of Boser's home fans.
Boser's UFC and regional experience against a much deeper level of competition gives him a durability and craft edge, while Diniz's kickboxing background and high finishing rate make him dangerous the moment the fight stays standing.
