Cage Warriors middleweight champion Nathias Frederick struggled with his footing in his first title defense at Cage Warriors 118 , but eventually planted his feet and scored a huge knockout to retain his title in London on Friday night. The event, which took place at the York Hall in the English capital, saw Frederick (9-2-1) take on Jamie Richardson in the main event, and the Birmingham native known as “Notorious” endured two frustrating rounds before finally connecting with a sledgehammer left hook that knocked Richardson (9-6) out cold seconds into Round 3. Things looked positive for the champion in the opening seconds of the fight, as Frederick dropped Richardson with his very first punch of the fight, a huge overhand right.
