RIZIN 54 will feature a featherweight clash between Patric Mix and Sato Masamitsu, with the bout officially added to the August 11 card. The matchup is scheduled under RIZIN MMA rules at the 61.0 kg limit and will be contested over three five-minute rounds.
The addition gives the RIZIN 54 card another notable featherweight contest, with both fighters set to compete at the promotion's standard 61.0 kg featherweight threshold rather than the UFC's 145-pound limit, reflecting the subtle but meaningful differences in how RIZIN structures its weight classes.
Why it matters
- The 61.0 kg RIZIN featherweight limit places this bout in one of the promotion's most active and competitive divisions.
- Three five-minute rounds under RIZIN MMA rules give both fighters a full championship-length format to make an impression.
- A strong performance from either man could have significant implications for featherweight divisional positioning within RIZIN heading into the back half of 2026.
