KSI announced he has vacated his Misfits Boxing title belt to pursue “other plans in the pipeline”.
The YouTuber-turned boxer launched Misfits in 2022 as a platform for celebrity-style crossover bouts.
In his comeback after three years out, he beat rapper Swarmz and Mexican boxer Luis Pinenda to win the cruiserweight title.
He defended it with a knockout over gamer Faze Temper and against nightclub tycoon and professional boxer Joe Fournier.
It was also on the line the night he lost to Tommy Fury – but he never actually conceded the title.
Now it appears KSI will not defend it again either after taking to social media to reveal it has been vacated.
He posted: “I have enjoyed the honour of being The Misfits Cruiserweight Champion immensely.
“I have other plans in the pipeline and it wouldn’t be fair for me to hold that title any longer so…
“I am relinquishing the belt and a new champion will be crowned on the next Survivor Tag!”
KSI, 30, took time away from boxing following defeat to Fury, 24.
But he recently confirmed he WILL return this year, eyeing a summer fight date.
Although a rematch with Fury looks unlikely after their bitter fallout following the controversial fight ending.
And a grudge match against Jake Paul, 27, also faces the KO amid a breakdown in talks between the camps.
