KSI watching Deji win his first boxing fight backstage is pure wholesome footage

There were crazy celebrations in KSI’s locker room as younger brother Deji secured his first boxing win on Saturday night.

Deji defeated Fousey on his sibling’s undercard at the O2 Arena, his first triumph in four attempts.

Big brother KSI watched on between victories over Swarmz and Luis Alcaraz Pineda, seemingly living every jab and hook.

The eventual TKO saw KSI punch the air as if he had won the fight himself, such was the pride he felt for his brother’s success.

Talking about Deji’s victory at the end of the night, KSI said: “Incredibly proud. This is one of the best moments of my life.

“For him to showcase his skill. He just took his time. Comfortably went in and out, jabbing and jabbing.
