KSI announced that he will be fighting YouTuber Alex Wassabi, August 27.
The bout will be held at London's O2 Arena. It ends KSI’s nearly three-year absence from the ring.
The Brit, aged 29, has not fought since beating Logan Paul in November 2019.
He is eager to put on the gloves and revenge his brother Deji who lost to Wassabi March.
KSI announced the fight via social media. He said, "I can't wait repeatedly punch the man with whom I have beef for years, laughed at for years, and the man who beat my brother. The man who has signed his death wish the moment we enter the ring."
"I am a different animal, and you will realize that fact on August 27, 2007"

Although Wassabi has not been defeated in the ring, many KSI fans still underestimate the 32-year old American.
One user wrote this on Twitter: "Light work JJ, teach JJ the lesson he must learn."
Another said, "Man, this isn’t fair at all." Alex is going to get a very unfair one-sided beating."
A third participant said, "I know this is for you to get rid the ring rust from your break." This is a dissapointing way to be an opponent in your comeback.
Deji, KSI's younger brother, will be on the show as an undercard fighter taking on YouTube prankster Fousey.
The fight will be live broadcast on DAZN TV PPV. The price has yet to be revealed.
