CES 55 weigh-ins took place from the Connecticut Convention Center. Fighters weighed in ahead of the first event held under regulation from the state of Connecticut. CES 55 being the inaugural mixed martial arts event held in the state, weigh-ins for the event were the first under the jurisdiction of state sanctions.
Unfortunately, not every fighter set for CES 55 made it to the scales. Two high profile bouts dropped from the card. New England prospects, William Knight and Fabio Cherant lost their opponents. According to Tapology, Carlton Little (Opponent of Knight) failed to show at weigh-ins.
